## Description

SOLAKAKA K21 RGB Backlit Tri-Mode Transparent Wireless Mechanical Number Pad Supports 3 Bluetooth/2.4GHz/Type C Wired,Hot Swappable 21 Keys Mechanical Numpad with Transparent Keycaps Black

Review: I really love this keyboard. It’s compact, looks amazing on the desk, and the color modes are just so fun. You can switch between different lighting styles, and they all look cool, not too flashy, just nice. The keys feel great when you type — soft and with a pleasant sound. It’s not loud, but you can still feel the click, which I personally like a lot. What I also love is how easy it is to connect. It works with USB, Bluetooth, or with a wire — and switching between devices is super simple. You just press a button and that’s it. I use it with my laptop and phone, and it’s really smooth. It’s honestly just a great keyboard. Does everything I need, and looks good doing it. I’m really happy with it and definitely recommend it.
Review: The quality of the keypad is very good, it's weighted, and the keys feel nice to press. I haven't tried any of the wireless modes but, plugging it in directly to the computer I've had no issues. Noise made by the keys is very quiet, no clicks. Love the different lighting effects! Overall, a great product.

*by M***B on 25 March 2024*

Went down this rabbit hole and tried about 5 or 6 different wireless keypads before I found this one. None of them were perfect but this one proved to be the best by far after I swapped out the keys for Gateron Blues. This one was the choice because: - Build quality is great: solid weight so it doesn't move around, quality materials - Keys were swappable so I was able to get the right click for my tasted - Works with MacBook (non negotiable for my needs) - 2.4ghz (more reliable than bluetooth) - Key layout is correct: a lot of the keypads have a weird layout that doesn't match a traditional keyboard number keypad section. So if you have been using one of those for years you would have to relearn it to use those keypads. This one had a layout which was close enough to normal (not 100% perfect though) - I didn't think I would care but the LED lights and translucent keys make for a cool effect Peace
