    • Works well, easily programmed
I use lots of high end imaging and voice-transcription software on specialized workstations in my field, which have many, many shortcut hotkeys combinations. For efficiency, I've been using a gaming mouse with ~20 some buttons which I've mapped many of these macros to. However, I still didn't feel totally optimized... Enter this keyboard. I now use it in combination with my gaming mouse and have nearly every function I use mapped to either the mouse or this device. Very handy, and very efficient. Some notes: -there are 23 keys, with 4 "layers" for each key. Each can be assigned a macro, keyboard key, or certain functions (volume up-down, etc) -however, you can only have 24 TOTAL recorded macros (that wasn't clear on the description) -the macros can be quite complicated, I have everything from simple "ctrl-del" to long string inputs stored as macros. -the program used to program the device takes a minute or two of poking around to figure out how it works, but after that it's fairly straight forward and fairly intuitive. The included instruction pamphlet is adequate. -everything is saved to the device itself so you can unplug and use it on many different computers without having to reprogram it each time (this was key for me). -only minor downsides I've encountered: 1) the base is kinda warped, so it it rocks a bit on a desk. Annoying but does not impact functionality. 2) the USB cable seems kinda low quality, and while it works for now I'm just waiting for the day I accidentally rip the end of the cable off by accident. Also not a game changer since you can order a generic USB cable any where if/when that occurs. Wish I had developed my current workflow setup earlier! Feels much more optimized now! ... show more

    • My favorite setup gadget! Perfect for productivity or gaming
Color: White/RGB backlit/Red switches
Review Image by qbin qbin
As a mechanical keyboard enthusiast, this thing is the perfect sidekick! For regular PC usage I leave it locked on a certain layer to use as a nav cluster, and for gaming I move my keyboard so that I have just the keypad and mouse in front of me to utilize the full space of my mousemat. It's pretty fun being able to whip my mouse around without worrying about crashing into my keyboard! I imagine it would also be super useful to map keyboard shortcuts for photo/video editing. There are a generous total of 4 fully programmable layers, with every key being addressable per layer. For users of custom keyboards, like 60%s running QMK, it should be completely intuitive to be able to shift up and down layers. One handy feature is the ability to "lock" (toggle) a layer, so it stays active without holding the Fn key. Macros are simple enough to work with, just remember which macro is which because you can't rename them. Also as other reviews have stated, you may have to split keypresses into up and down if the macro involves holding a key down while pressing others. RGB is SUPER bright. The LEDs themselves are brighter than any of my other keyboards, and it is only further amplified by the acrylic case and white keycaps. Customization is limited, with the only animated modes being breathing, blinking, and a rainbow wave, but you can at least choose what colors to go through. You can also set it to change to a certain color when an Fn layer is locked. Included in the packaging are what appears to be a full set of white doubleshot keycaps, as well enough extra blank keycaps to cover each key. Honestly, my only complaint at all is with the Outemu Red switches. They're scratchy, have crunchy springs, and the bottom out feels mushy. However this doesn't have to be an issue if it really bothers you, as you can always just desolder and put in new switches. I personally installed holtites for my WASD keys to make them hotswappable, since those are the only keys that I would really care how they feel, and Kailh Box Reds are an infinity% improvement (just note that you'll need switches with the big rectangular LED cutout because the SMD LEDs protrude from the PCB). I have not had a single issue with the hardware or software; it worked right when first plugged in without having to fiddle with any drivers, every switch works, and every key does exactly what I program it to. Finally, the value for this little keypad is amazing! You get better programmability than the ones from Razer/Logitech at like half the price, and I'd argue that this one has the best form factor as just a slice of a keyboard instead of a literal numpad or some terrible claw shape. If you're in the market for a keypad there's no reason to look elsewhere! ... show more

    • Great build quality but disappointing implementation.
Color: Black/Blue backlit/Red switches
Refers to Koolerton 23 Key keyboard (Blue Backlight / Red Switchs) this is really a mixed review. There's a lot to like here and this might be perfect for some applications. But in my case, there are a lot of down sides too. Lets start with the things I like 1) Excellent build quality. Feels solid. Worked perfectly out of the box. A+ here. 2) Very high quality USB cable came with it. Another A+ 3) There are 4 layers, so in reality you can map up to 96 different keys (23 x 4). 4) Full set of Black keyboard keys with transparent letters, perfect for the backlit keys 5) 23 extra blank white keys. 6) Included keycap puller 7) Actual usable instruction pamphlet included with it. Who does that these days! Very nice touch. Like it. 8) Software worked well (on an up-to-date Win 10), no problems running it and connecting to the Keypad. 9) Running the software on 2 PC is possible. When moving the keypad to the other PC, just connecting to the keypad will download the config from the keypad into the software for changes. No need to transfer config files from one PC to another. Now for the list of things I didn't like (or could use improvement): 1) The software for programming the keyboard is a little quirky but nothing too difficult to figure out with just a little trial and error. 2) Clicking the "Upload" to keypad button only uploads the section you're working on. ie. changing the keymapping upload will not upload the macros. You need to upload those separately. Just a quirk to learn 3) Each key can be programmed with either a single keystroke or a macro. By single keystroke, I mean one key-press. If you want to do a combination keystroke, like Win+L, that's 2 keystrokes. Tp do that you need to use macros. 4) You can assign a "Macro" to a key press. But you're limited to only 24 macros. For your macros, 12 of them are "Quick Macros" limited to 24 chars max. And 12 are "Custom Macros" which are limited to 42 chars. Remember, pressing Shift, Ctrl, Alt, or Win key modifiers consume one of your precious few characters. 5) Remember, with the 4 layers, you really have 92 programmable keys but only 24 macros. That limits the usefulness of the keyboard as the remaining 69 keys will need to be single keys, same as on your normal keyboard. 6) Given the limited size of each macro (24 or 42 chars) and only having 24 macros available, the usefulness is limited. 7) Macros can contain other imbedded macros, so you could work-around the 24 or 42 char limit, but you'd be using more of your precious few macros. My intent was to store fairly long strings of frequently repeated keystrokes. This is just to limiting for that. Things for improvement: 1) Increase the size limit on the macros to at least 100 chars. 2) Increase the number of macros available. 92 sounds like a good number :) 3) One missing feature that would be nice to have in the software is a Macro recorder. Would be nice to have it record my keystrokes as I work instead of making me enter a series of keystrokes manually. So there you have it. Its a well built solid product. But has a lot of drawbacks when it comes to taking full advantage of an otherwise excellent product. ** Update 1 ** I noticed a weird quirk. If Caps Lock is set ON on your main keyboard, the Caps Lock will also apply to any key or macro on this keypad as well. Kind of defeats the purpose, especially if you have passwords stored on this keypad. ... show more
