Style: 39 Keyboard Black
Really happy with this purchase, still trying to train myself to use it as much as I can. I got this for the number of macros it has compared to others. The software has a bit of a learning curve but their are some videos out their to help. Also, occasionally I have to unplug it to reset, and I haven't figured out the knob, but that wasn't a deal breaker for me.

Good programmable keyboard that can use some improvements. Pros: All 23 keys are programmable. Can map simultaneous key presses i.e. (Lshift-Ralt-a) to a single key Really good USB cable - feels solid and nice to the touch. Comes with a complete set of extra key caps and key remover Reasonably decent programming instructions though there is some experimentation needed to figure out the quirks. LED glow on the black keys looks fantastic. You can map up to 4 sets of key mapping and toggle between them if you reserve a least 1 key to do the toggling. Two of the key LEDs can be programmed to act like a status indicator to indicate which key map mode you are in (i.e. white instead of blue) Cons: All the black key caps are tapered by different amounts. If you arrange the different letters to be on the same row of a standard keyboard you are ok. But if you put say the F4 key cap on the same row as the X key cap you'll find that they are not of even height which is annoying. It would have been better if all the keys had the same profile so you can truly mix and match. The white key caps look ugly with the LED on. The illumination through the white plastic does not look even. Though one can program up to 4 different key mappings, it is hard to fully take advantage of it since there is only 24 macros that you can define. You can map lower case keys directly without using up a macro. But if you want to map simultaneous key presses such as Ctrll-c, $ (Shift-4), A (Shift-a) you need to use a macro. So you quickly run out of macros. I think a product improvement would be to either allow simultaneous key presses to be mapped without a macro, or increase the number of macros supported. Overall it is a good product despite some shortcomings.

Took a little time to figure out the software. Lots of online tutorials to help you understand it. Plenty of keys, with a fn key and 2 fn toggle modes means you could map a ton of keys and macros to this thing. For example, I mapped a bunch of the shortcuts I used to the normal mode, my Zoom shortcuts to the f2 layer, and my Teams shortcuts to f3. The same keys start and stop audio and video, share screen, and swap cameras and displays. I also have persistent keys set on all layers for screen clipping and cut/copy/paste. Pretty convenient. I also love the macro feature. While you can't record macros on the fly, the software (amag) allows you to define some pretty substantial macros with key sequences, time delays, etc. And assign them to keys. It also completely stores the profile and macros in onboard memory, so I can program it on my personal PC, and use it on all my work PCs. No driver issues, it just shows up as a keyboard. (Note: I can't program with one of my work PCs while it is plugged into a thunderbolt dock. The scant documentation kinda hints at it, but it explains why I have trouble programming it sometimes) (Note: software is standalone and portable and does not require installation or elevated permission to run) It comes with an almost complete set of keycaps of the different profiles, which is annoying, cuz they have regular symbols on them, double shot so the LEDs can bleed they, but you'll probably want a consistent flow of keycap angles, which limits certain keys to certain rows. It also comes with a bag of flimsy all white keycaps, all the same profile, that look good, but don't feel as nice as the mx caps. There are 2 status LEDs under the top row center keys (1C and 1D) that by default are num and caps lock, but they can be repurposed as f2/f3 status indicators too using the software. They are close to the same brightness as the backlight at max, so it's hard to see at full bright, but visible at lower bright levels.

Unsupported on windows 10, Customer support nowhere to be found. Purchased about a week ago. Manual states I need to install macro programming software- fine. I followed the link in the paper manual to a dead site with sketchy files that my anti-malware flags multiple times, and ultimately refuses to open even when I bypass my firewall. A different URL on the box takes me to a similar site with software that downloads, but refuses to recognize the keyboard, even when it is plugged into different USB ports on which other keyboards and peripherals run just fine. The Koolertron website is similarly difficult to navigate, and has a third, distinct set of software listed for this keyboard. The guide and provided videos offer little information on how to use the software, and absolutely no debugging info. The third software ALSO does not recognize the keyboard. Great. So, I email the support email address printed on the box and the amazon listing. 3 days later, all they have done is take my order number and redirect me to a different department, which has since ghosted me. In summary, DO NOT BUY this keyboard! The software does not work, and the pcb uses some weird 3rd party drivers, so regular macro programs also do not recognize it. Customer support is nonexistent also, so the keyboard is more or less inoperable.

Once I figured out the hair pulling task of downloading the software, it works great! Assigning keys is easy. Assigning macros is easy. I use it for AutoCad. I assigned the most common functions to the keyboard. Plus a number keypad.
