I seem to be the tip of the spear when it comes to Aliexpress tier mechanical numpads (see my original GK21 review here ). I'm going to try to keep this one brief. This thing has it all. Features: Wireless mechanical numpad, both Bluetooth (3 connections) and 2.4Ghz with dongle. The 2.4Ghz dongle is a big plus because it'll always be 'awake' and ready to roll when you are, no pairing issues or delays like I had with the GK21. Hotswappable switches (!) Full stand-alone calculator functionality with screen. Switching from calculator mode to 'computer' mode is done with Fn + Esc. In 'computer' mode it talks to your computer and the calculator screen stays blank. In calculator mode, the outputs are fed to the calculator screen. Two spare USB-A inputs to make it act as a USB hub when wired (fed through USB-C). The USB-A inputs double as a dongle holder for added portability (nice). I'm a fan of good quality plastic cases and this is one of them. It's lightweight but thick and makes the whole unit feel like something you can depend on, chuck in a bag, or shove around your desk without having to worry about anything. Nice retro-ish look with attractive LED indicators for battery, numlock and wireless (illuminated in red, white and green respectively). A satisfying on/off switch in the back (lacking in the GK21, you had to wake with a keypress and wait for it to re-pair via BT for a second. Not a huge deal but that small delay made it slightly annoying to use on the fly). Good price ($40!). It shipped to me in just a few days from AliExpress. It has RGB (but I turn it off). $, € and ¥ characters under the function layer. Cool. Drawbacks: The stock linear switches are some kind of Tecsee branded white square-ish stem on almost translucent yellow housings. I'm not familiar with that make but these are easily the worst switches I have ever tried (and I've tried quite a few), mushy and very shallow travel. Thankfully the PCB is hotswappable so those are getting replaced asap. I don't mind too much that it has this smoky transparent body. However I am not very fond of the slight glitter it has. It's not too bad (not like your little sister's phone case), and from a normal distance you could be fooled into thinking it has some kind of rough finish. It doesn't take away from its 90s look (maybe it adds to it). But yeah, not a fan, and it makes the unit very hard to pair with any keyboard on the market. Simply put, no keyboard I've ever seen has this clear smoke + glitter case. Oh well. It doesn't have a 2u zero key, instead it's got a '00' key that outputs double zero when in calculator mode and becomes an equal key in computer mode. Might not be a drawback for you but I slightly prefer the larger classic 2u key and this might make it marginally harder to find a compatible keycap set for it. The tall PBT keycaps which I picked over the low-profile ones are fine (sharp legends) but I can feel the legend prints over my fingers so I'm guessing some kind of pad printing that won't last too long. But that's the beauty of mechanical keyboards, you can slap on your favorite MX-compatible set. No key remapping. Point to GK21 for having that feature. No 3-digit spacing indicator on the calculator screen (it'll display 1,000,000 as 1000000, forcing you to count the digits sometimes), ends up being more annoying than I would have thought. For the price and feature list, I fully recommend it. It's strictly better than the Ducky Pocket mechanical calculator numpad because a) wireless [2.4Ghz!] and b) hotswap. I just wish I had a DSA Scientific set to pair with this. Will probably slap SA Symbiosis or SA Oblivion on it after I put some clickbar switches in it. More on reddit.com
