One Handed RGB Mechanical Keyboard, Koolertron 23 Fully Programmable Keys and Portable Mini Macro Mechanical Gaming Keyboard with Blue Switches and Adjusted RGB LED Backlit

Build quality - Very solidly made, remember to stick the included rubber feet on or the keypad will slide around and transmit spring sounds onto the table. RGB LEDs work very nice and are IMO look very nice on the frosted/translucent body.Switches - OUTEMU blue switches, Cherry MX blue clones. They are clones but they are quite popular in the mech keyboard world (if you search you'll see many people comparing them), and in my opinion feel quite similar to MX Blues, perhaps a touch heavier and a bit clicker. Don't let the fact that they are clones put you off, these are nice.Included keycaps - Very generous with included keycaps, they have included everything on a normal keyboard that is 1 unit in size, double-shot keycaps. Good quality. They also include a set of blank keycaps, these are very bad quality (shape and finish are bad, don't fit very well) and would recommend against using.Software - To those who are computer-inclined like myself they took a bit of trial and error to understand how the Macro program works, but it was part of the fun. Might be too confusing for those who aren't though, although manual included (pdf) is reasonably clear and might be able to figure it out.RGB - Options available are Rainbow, and 3 other programmable colours that you can toggle from. Can't individually programme the colour of each key.Conclusion - This is a very cheap and cheerful piece of kit that works as advertised, and works very well. £40 isn't exactly cheap but is probably the cheapest mechanical macro keypad out there by a mile. If you need a mechanical macro keypad that feels like MX Blues - would definitely recommend this.

The software is oversimplified. Cannot name macros, and layering (more than one function for the given key) just doesn't work. The RGB colours are mostly useless, just keep it on white or off.Also, when it says that there are 12 macros, what it means that there cannot be 13. What a bummer.Otherwise, the system works OK in general. The key quality is good, with a loud tactile mechanical click. This style is trendy today, even though I would personally prefer them to be rubbery silent. key tops are easily replaceable with a supplied tool, or even without it.I use it to aid code debugging and navigation - using real buttons instead of complex key combinations. Works fine for me.Overall, a bit pricey, but ultimately does the job.

Perfect for gaming

Really improved my productivity with photoshop, matches my white rgb keyboard well, confusing to work the macros at first but quickly got used to it. Additional keycaps are a huge bonus, the blank keycaps are bad quality but thats not much of an issue
