Got this from Aliexpress. and i can attest that this is one of the best hotswap wireless out there.
I use it wired or wireless without any problem. very intuitive to use. the software makes it even more amazing, you can customized the RGB lighting all you want, eventhough i don't really care about RGB.
But you can customize this lil' numpad to be a macro board. as a professional colorist and VFX artist, it's really helpful. you can switch layout with a shortcut easily. highly recommended. and it's also comes with a nice lil' pouch.

smartazz104I'm assuming the wireless capability and the solid metal case adds cost. Also gotta factor in that they sell less numpads than keyboards so they increase the price to make up for it
BurbleAndPopIt must be the last reason; I picked up a hotswappable TKL from KPRepublic with Bluetooth and metal case for around AUD$90 (about 100 currently). They have this exact item as in the link from a previous comment for around AUD$140. Here in Drop it’s the equivalent of about AUD$120.

Are you sure you used a GK21S? This numpad is all but intuitive and the software is pure junk. I've tried to customize a key to act as a Ctrl+Alt+num.0 and it refuses to do it. Ctrl+Alt+5 works alright. Any customization is a thousand tries to make it work. If you could use the software, the community would thank you for posting a tutorial or an instructive manual.
