Printed October 3, 2025
It is a coincidence {that a} bunch of 75% keyboards have piled up in my evaluate schedule, however no less than we will evaluate them first-hand now. After dissecting the comparatively costly Evoworks Evo75 (and earlier than attending to the Womier ERA75 and KiiBOOM Jade 75), right here comes most likely probably the most reasonably priced alu 75%: the Redragon Eclipse K720 Professional. As traditional, with full disassembly and teardown.
TLDR; The tri-mode wi-fi K720 Eclipse Professional is a completely constructed keyboard coming in a hefty aluminum housing. It is a very reasonably priced mechanical keyboard ($90 with the KBDNEWS coupon code) with some premium options. OLED display screen, rotary knob, good ornament lights, lovely double-shot keycap set, and funky switches. Gaskets and many sound dampening layers guarantee an honest however very direct out-of-the-box typing expertise. The hotswap PCB and MX-compatible switches make it considerably customizable regardless of the constraints of the proprietary software program. All in all, the K720 Eclipse Professional is a pleasant provide for a seemingly unbeatable value – not for keymap wizards although.
As you may see, I’ve eviscerated the K720 to the very core as traditional. Try the complete evaluate beneath for all the small print and photographs revealing its internals as effectively. 😉
Disclaimer
Redragon was sort sufficient to ship me this evaluate unit totally free, which can introduce all types of biases – each unfavourable and optimistic in my expertise. Take all the things I write with a grain of salt.
Unboxing & Contents
The outer cardboard field of the Eclipse K720 Professional is fairly stylish, and there is a way more puritan internal cardboard field too. It is a a lot less complicated bundle in comparison with the Evo75, however we’re speaking about $90 vs $150, in order that’s comprehensible.
Contents:
- The K720 Eclipse Professional, pre-built with switches and keycaps.
- Fast-start information, Redragon sticker pack.
- 2.4GHz receiver (magnetic compartment within the case)
- easy USB cable
- fundamental mixed software to take away keycaps and switches
- 4x spare switches (no further caps for Mac)
First impressions, design language
The Eclipse K720 is available in a single, fairly common colorway: matte black aluminum case with Olivia-ish keycap colours – two-tone darkish gray plus gentle rose accents.
One other coincidence, however identical to the not too long ago lined Nebula Evo75, the K720 incorporates a glittery end too. The micro-glitter impact is sort of onerous to seize in photographs, as a result of it is extra refined in comparison with the Evoworks end (click on the picture beneath).
The Redragon emblem on the entrance is a bit intrusive for my style, however in any other case I like this easy however authoritative design and aesthetics, spiced up by some good rounded cuts and the RGB gentle strips on the 2 sides.
It is onerous to face out in such a crowded market just like the 75% section, and the K720 Eclipse Professional apparently tries to realize this through the colourful OLED display screen, rotary knob, and these fancy ornament lights – and I’ve to say that this works.

- Keycaps: double-shot PBT, a excessive, sculpted, spherical profile
- Switches: Redragon branded linear
- Typing angle: 6 levels
- Construction: gasket mounting
- Stabilizers: plate mount (no screw-in stab assist)
- PCB: hotswap, north-facing(!) per-key RGB
- 1.41″ display screen
- rotary knob
- Connectivity: wired, 2.4G wi-fi, Bluetooth

- Battery 4000mAh
- Materials: CNC-machined aluminum

- Weight: 1,592g
Format
The 75% structure is fairly customary these days. It means no numpad and no traditional navigation cluster structure both, nevertheless, you have got arrows, perform keys, full quantity row, and a part of the traditional navigation keys.
It is a comparatively compact design (ANSI), that includes 81 keys, optimizing area whereas guaranteeing that each one important capabilities are simply accessible for brand spanking new customers transitioning from e.g. a fullsize keyboard.
Many 75% keyboards function a couple of much less or extra keys. The 75% K720 Eclipse Professional, with its 81 keys, isn’t cramped in any respect. The arrow cluster is simple to find when contact typing: there’s not simply the little hole on the left, it is truly properly offset the 1800 fashion – you aren’t getting misplaced when altering between the house row and arrows.
As well as, the K720 retains the hole between the F-groups – generally sacrificed by comparable boards.
The additional column on the fitting consists of 4 keys.
Keycaps
The keycap set appears very nice, it is a confirmed colorway within the mechanical keyboard group. It is a double-shot PBT set, nevertheless, with sparingly used materials in some instances. That mentioned, the quantity of fabric by no means impacts legend high quality.
I am not completely certain in regards to the keycap profile, so let’s solely say that it is a sculpted, spherical one, comparatively excessive.
With reference to keycap compatibility, the 75% structure ought to be extensively supported in case you go for one thing totally different.
Switches
The switches are good too, Redragon branded gentle linear switches in a wild deep yellow shade. I might say that the wobble is appropriate, nevertheless, it is amplified by the excessive keycaps.
Knowledge on this noname (‘Hello-Fi’) swap is sparse:
- Actuation pressure: 40gf
- Pre-travel: 2.0mm
- Whole journey: 3.3mm
That mentioned, the switches really feel first rate, however the PCB options hotswap sockets anyway, so you are not restricted to the manufacturing facility setup in any respect. Try the trending community-favorite switches, or be happy to make use of your private favorites laying round.
Perhaps it is the comparatively onerous, direct typing sensation, however I really feel that this setup would work higher with tactile switches – with the premise of avoiding bottoming out.
Construct high quality, construction, case
This board is fairly heavy, as it’s anticipated from a CNC aluminum case. 1.6kg to be actual. It is from being the heaviest 75% keyboard I’ve ever reviewed, however nonetheless undoubtedly hefty, and also you undoubtedly do not want extra heft: there isn’t any approach it can transfer round when gaming, not even mentioning much less demanding jobs.
The construct high quality is first rate. The entire thing feels heavy obligation, with out being overly subtle – which might be simply out of character with a board like this mannequin.
Typing angle: mounted, 6 levels.
Disassembly? I have been actually spoiled by all of the not too long ago examined easy-to-open ball-catch keyboards, however managed to disassemble this Redragon anyway.
It’s a must to take away 6 screws, 4 of them after tearing up the bumpons. Yikes.
Construction & Mounting
The K720 Eclipse Professional options gasket mounting (the gaskets are hooked up to the plate), nevertheless, this construction differs a bit from different gasket options because it makes use of a a lot tougher materials than traditional. So I might say gaskets right here have a restricted impact. Delivering a crisp, very direct, clear typing really feel, so I am unable to actually really feel that a lot flexibility or softness – the final hallmarks of gasket mounting.
Plate
The plate is absolutely clear PC, which is an unusual however good selection, even when it reveals some unusual empty areas contained in the plate/foam/PCB sandwich – because of the foam’s form. As well as, the plate options flex cuts for flexibility.
Plate-mount stabilizers, that are very wobbly. As if the plate can be thinner than for what the stabs had been designed for.
PCB
The PCB is a part of the thick plate/foam/PCB sandwich, and it comes with hotswap sockets, north-facing(!) per-key LEDs, and no flex cuts.
The default stabs are plate mounted, and the the PCB would not assist screw-in stabilizers because it lacks the mandatory holes for them.
However, there are indicators of ISO-support, e.g. in case you take a better take a look at the left Shift half, but in addition across the Enter key. Nonetheless, for the reason that further hotswap sockets will not be soldered, it’s important to seize a soldering iron to check if the software program helps it too.
Show
LCD? OLED? TFT? These phrases are thrown round on the product web page and in varied supplies interchangeably.
Anyway, the 1.41″ shade display screen shows the date and time, battery stage, connection mode and CapsLock/NumLock standing. It auto-synchronizes with the host laptop’s clock on the primary use of the software program I suppose.
The show additionally serves as a software for adjusting varied settings – you possibly can navigate the menu through the rotary knob. As well as, you possibly can customise the display screen with photos and animated gifs by utilizing the equipped software program.
Rotary knob
The rotary encoder decreases/will increase quantity by default, and urgent it serves for navigating the menu on the display screen – in distinction to the frequent mute performance.
Weight
No fancy ornament weight, only a plain, uninterrupted backside with the glitter – however that is okay. The K720 Eclipse Professional remains to be heavy sufficient, and you do not typically stare on the backside of your keyboard, do you?
Sound & Sound dampening
Thick 3.5mm PO sandwich foam, IXPE swap foam, PET sound pad, and two extra layers within the backside case: one for the hotswap sockets and different components, and one other silicon dampener. Along with the TPR gaskets and the versatile PC plate with the cutouts, the K720 Eclipse Professional ought to present a a lot softer and cozier typing really feel, but it surely doesn’t. It is okay in case you favor the direct typing really feel.
Lights
This keyboard is supplied with south-facing per-key RGB backlighting with loads of out there colours and patterns. You may cycle by means of all of the choices through FN key combos, the dial/display screen, or you possibly can fine-tune it with the devoted software program.
As well as, there are the 2 “ambient gentle strips”. So far as I can see, there isn’t any method to customise them or flip them off, however they’re good anyway. Nicely, you possibly can’t see them in any respect whereas sitting in entrance of the board and typing, so they’re undoubtedly an arrogance function.
Wi-fi
The K720 Eclipse Professional is a tri-mode wi-fi keyboard (Bluetooth 5.0, 2.4GHz wi-fi, and USB Sort-C wired connections) powered by a 4000mAh lithium battery.
The bodily connection mode selector swap subsequent to the USB port says ‘OFF’ as a substitute of ‘USB’ – unsure about full battery decoupling although. No bodily battery on-off key beneath any keycap.
Common warning: When you use your wi-fi K720 Eclipse Professional keyboard completely related, please learn this text about Constructed-in keyboard batteries and learn how to keep away from fireplace – for particulars, suggestions, and horror tales.
Principally, maintaining the board plugged in always might result in accelerated degradation of the lithium battery. It’s a must to observe correct battery care practices, so you must take away, disconnect or swap off the battery in case you do not want wi-fi performance. Test the battery for swelling repeatedly, even when disconnected or eliminated.
The K720 Eclipse Professional would not make this course of simple. There isn’t any bodily swap to disconnect the charging circuit and successfully isolating the battery from the PCB, so monitoring battery well being shall be a problem.
Software program
Proprietary Redragon software program. I am not very fond of putting in unknown software program generally, particularly within the period of the quasi-standard QMK, VIA and Vial, and particularly one which makes my antivirus/firewall software program throwing up all types of alerts. However I gave it a attempt anyway.
If the manufacturing facility settings do not meet your wants, be happy to customise your keymap by downloading and putting in the software program right here (down beneath on the web page). Nicely, solely if you’re on Home windows. Whereas the keyboard itself helps Mac, there isn’t any Mac driver.
Some letters swapped
Swapping letters or symbols works as traditional, it is fairly simple. Nonetheless, there isn’t any method to implement SpaceFN due to the dearth of layer mod-tap capabilities. In idea, there are two further layers, however you possibly can solely entry them through the devoted FN1 and FN2 keycodes.
I attempted utilizing the CapsLock because the layer toggle, however Area would make a lot extra sense. A single, easy-to-access SpaceFN layer is essential for a lot of customers as you would put arrows, navigation and numbers beneath your fingertips. For this impact, you may must resort to third-party options with the Eclipse K720 Professional.
Portability
The K720 Eclipse Professional is a superb board for stationery use, but when portability is your major concern, I’d select one thing a lot lighter. Positive, its wi-fi options make it cellular in idea, being extra compact than a fullsize board helps too, nevertheless, perhaps one thing smaller or no less than lighter than 1.6kg is best fitted to on the go. 😉
Comparability
From all of the CNC alu 75% keyboards, the K720 might be probably the most reasonably priced with its value of simply $90 (utilizing the KBDNEWS coupon code).
That mentioned, if we wish to evaluate it to the not too long ago reviewed Evo75, we needed to take into account some necessary variations like: OLED and knob vs. hardshell case, F13 key and mud cowl. Additionally Cherry profile vs one thing a lot greater double-shot. The out-of-the-box typing really feel of the Evo75 is outstanding although, no different prebuilt board comes even near it in the meanwhile. You must determine if that is price the additional $60 for you.
Different 75% boards, typically within the $120-130 value vary and beneath, are quite a few. Try the fashionable NPKC RO75, the foolish (plastic!) KiiBOOM Phantom81 and extra severe Moonshadow V2, and even the GravaStar Mercury K1 Professional (wired) – and check out to determine what options you discover necessary: alu case, rotary knob, offset arrows, wi-fi, or just aesthetics.
The Womier ERA75 and KiiBOOM Jade 75 – with comparable layouts – would be the subsequent boards I’ll evaluate, in order you possibly can see, the market is fairly crowded.
Conclusion
The 75% wi-fi Redragon Eclipse K720 Professional is a really reasonably priced pre-built mechanical keyboard with highlights like a hefty aluminum case, OLED show and rotary knob. The double-shot caps are good, identical to the Redragon branded switches. Nonetheless, regardless of the gaskets and all of the sound dampening layers, the out-of-the-box typing expertise could possibly be improved. It is an amazing provide for the target market, nevertheless, the proprietary software program make it much less interesting for actual keymap wizards.
Professionals
- sturdy aluminum case
- double-shot keycaps with good colorway
- customizable (hotswap, MX)
Cons
- proprietary software program with no layer-tap capabilities
- wobbly stabilizers – an oxymoron?
- cable: this board deserves one thing higher than the essential cable coming within the bundle, however the gap within the case is simply too small for a lot of different cables.
