EPOMAKER EK21 VIA Gasket Number Pad, Bluetooth 5.0/2.4ghz/Wired Hot Swappable Numpad, with Poron Foam, Aluminum Alloy Knob, 1000mAh Battery, Programmable for Win/Mac/Gaming (Epomaker Flamingo Switch)

When in 2.4ghz mode, rather than BT, the battery life is phenomenal. I use this multiple times a day and even have the back lighting on when in use and have only had to plug it in to charge once every few months. It's a USB-C connection when I do need to plug it in, which is great since most modern devices are, so a single USB-C cable can charge this or any other devices on my desk when they need it.No (noticeable) input lag and in 2.4ghz mode I've never had any connection issues. A few connection issues with bluetooth but I suspect that is a motherboard BT module issue, not this device.

First off for the price it's good. Trying to program it has been a bit of a pain though, you can get it to work but I found it to be a very finnicky process, as the config file would load in but wasn't properly mapped. The hot swap sockets are there but it was a pain to swap them out. I put in pandas and it required a full teardown. The included key pulled was not sufficient to remove all the switches due to stabilizers interfering. My own keypuller did not work either. I just took the entire switch plate off and used a spudger to nudge the releases. Pushing in new switches also didn't go so well. The plate was not consistent and I found that sometimes the holes would be very tight and other times they'd be too loose. The amount of flex with the lack of any supports made it quite difficult. What I did was push all the switches into the plate and then press all of them into the hotswap sockets at once while installed on the plate. Keycap quality was kind of ehh too. Quite a few of them had some excess mold flash that I had to trim with a hobby knife.Once everything was done, I found the experience to be good. Sounds and feels good. Just know that if you're buying this with the intention to customize it in any way other than replacing keycaps then it may be a bit more of an endeavor that advertised.

Recently I was wondering how I could increase my workflow and not at all cater to my lazy needs. At first I was worried I was just wasting my time and money on something so frivolous and simple as a second numpad. Little did I know I would soon use this all the time and actively try to figure out more ways I could use it.Actually managing to remap the keys with the program they suggest was a journey, though. The manual hardly helps and I thought I’d save people some grief and provide pictures with some quick steps at the bottom of this review to get it working.Pros;- tickity tack tack (thock) ta(ta)ck(tac) t a c k- Comes with everything you need including a cute handy tool to remove the caps and switches.- Doesn’t matter what you need to connect to, it can connect to tablets/iPads, PCs, you name it.- Many many many remapping capabilities from macros to the sacred F13-F24 keys, even media keys for music and videos.- The knob is amazing and can even be remapped, too! Clockwise is one key and counterclockwise is another key while also having a key for pressing the knob.- Battery life lasts a long while and charges very quickly to boot.- It’s a bit chonky but I kinda like it. It fits in my bag just fine but if you have a small bag you might need to make some space.- The material seems sturdy enough to take quite a tumble and the keys and knob feel wonderful.- The backlight is very nice and some of the settings for the patterns are so pretty. You can also dim it, change saturation and hue, or turn it off entirely.Cons;- The ergonomics don’t ergonomic too good at any other angle other than flat on a surface but it isn’t a huge deal. I like to draw in bed and I got big meaty claws so I have to use this at an angle or rest it on a pillow with my arm.- For some reason I swear this thing said it had multiple profiles you could switch to but by default they’re more like “layers” that are temporarily switched to by holding a button BUT you can treat them as profiles by using the TO(0)-TO(9) keys in the Layers section of the remapping program. The default bluetooth switch seems like profiles but are actually just different bluetooth profiles in case you’re using multiple devices and don’t feel like making them “forget this device” every time you wanna switch.- It would seem as though the knob’s clockwise and counterclockwise can be remapped but can’t be changed with a different Layer unless you use the Fn1 or Fn2 keys. Otherwise it’s always whatever it’s been mapped to in Layer 0.- I nearly blew a gasket figuring out how to remap the keys. The manual is of no help whatsoever other than showing you where and what to download. I decided I’d provide some steps and pictures to hopefully help some people.After you’ve downloaded Via from the github and the .json files the manual tells you to download,1.) Click on Settings2.) Enable “Show Design Tab”3.) Head over to the Design Tab4.) Enable “Use V2 Definitions (deprecated)”5.) Click Load and load one of the .json files for whatever you’ve connected the keypad to your computer with. (2.4G = Dongle, USB = USB C)6.) You’re good to go, in the Configure Tab you should see the keypad now. Sometimes I need to restart VIA and then it’ll see it. Make sure you loaded the right json for your connection and not both. There isn’t a .json for bluetooth for some reason.
