8BitDo Retro 18 Mechanical Numpad, Supports Calculator Mode, Bluetooth/2.4G/Wired Numpad for Windows and Android - N Edition

Good one so far

I recently got a 75% keyboard since I don't really use a Numpad a lot, however, when I do need a Numpad, I do need it! (Especially for software like Blender, where controlling camera angles become much easier with a Numpad). I also use a Numpad extensively when using the calculator on my desktop. This product was exactly what I needed. I keep it on the side connected by 2.4G and its so easy to just open it, use it, and close it again. It's wonderfully designed, the keys are satisfying to press, and it has a good quality build overall.
