CIDOO V21 VIA Programmable Gasket Number Pad, Aluminum Numpad, Bluetooth 5.0/2.4ghz/Wired Hot Swappable Numeric Keypad, with Knob, 1000mAh Battery, Poron Foam for Laptop Mac Win

I picked this up after purchasing the NES 8-Bitdo keyboard, and I'm glad I did. This thing is SOLID. I mean, it could be included as a weapon in a game of Clue. The construction is solid steel, the keys feel great and are very fucntionally responsive, and bluetooth connectivity is absolutely reliable in addition to the wired and wireless dongle connection options. You simply plug in the wireless dongle to your home desktop, and that is as easy as it gets when setting up this device. The battery lasts forever, it looks great with it's backlight, and is worth every penny.

EPOMAKER CIDOO V21 Pro Pros: Bluetooth – no adapter needed, but it does come with one Typing Quality – this is the winner right here. By far the best keypad I tried. It feels and sounds amazing. I want to type on it just for fun because it feels and sounds so good. Sound – it sounds amazing. It is not super quiet, but for me, this is what a keyboard should sound like. It is very pleasant to listen to Customizable –programmable and I can move around the keycaps and hot swap the switches Cons: Size – this thing is a brick. No joke, it probably weighs as much as a brick. It is too big too big and heavy to consider traveling with When I first picked up the box, I couldn’t believe how heavy it was. I immediately thought I wasn’t going to keep it because of the weight, but after unboxing and trying it a little bit I couldn’t stop thinking about how nice it is to type on. Trying the other keypads just couldn’t compare to the feel and sound. This is the one I ultimately decided to keep. It was the most expensive but personally I think it is worth it. I will not be traveling with it, but I am going to try and limit my work when traveling anyway. Context: I recently started a remote job that I need a number keypad, and my work laptop doesn’t have one. I couldn’t decide which one to get so I grabbed several different options to try. Things in order of importance to me: Bluetooth (not a 2.4 Ghz adapter because I want to keep the USB ports open), portable (I might have to travel with it), sound (not too loud in case I am working in a public space), typing quality (preferably mechanical switches), and customizable (hot swappable keycaps and switches and maybe programmable). I didn’t extensively use each: I assume all of them work so I tested most of them without connecting them.

Bought this and the V87 separately. Both are amazing quality builds for the price. The Keycaps are fantastic, and the matte switches are actually pretty great too. Removed a star, because trying to modify key layouts on these has been very difficult in comparison to the Keychron Q series boards I have used- which are detected automatically by the VIA app and have been simple to adjust. Both the CIDOO V87 and this V21 are not recognized by the VIA app, and the sketchy downloadable files from the Epomaker site have not really worked reliably for me... If you want the default functions and light effects, and want to use it as a numpad alone, it's fantastic- but as a macropad, I'd avoid it.

I explain in the video, so please watch. Any springy or metal/mechanical sounds picked up in the video ARE NOT heard in person. I only noticed after editing the video. Very smooth sounds with no feedback, if you’re okay with that. I am impartial to GAETRON brown switches as they are silent with feedback, but on a number pad, it doesn’t bother me, mostly because this keypad sounds like butter. My husband isn’t really into keyboards like I am, and even he was impressed with how this thing sounds and feels. I’m pretty frugal, and even I believe the build quality is worth the money.

It's built like a tank, seems to be metallic all around, works like a charm, it's weighted, feels so good quality. the keys sound nice. It's expensive but it's easily the best numpad out there. My only quirk is that the cable is shiny white and not closer to the color of the keyboard, or even black. but anyway I love this number pad.

Great product extremely robust very well made great craftsmanship, if I had picked up this brick in a store I would’ve expected it to be like 200 bucks, smooth butter keys great finish warm construction. Excellent quality.

Great numpad with mechanical keys. Good connection options (bluetooth, 2.4 ghz and USB). Quite heavy, which is a plus to me. I don't understand the leds much as they are not very functional. But other than that, a fantastic numpad.

First of all, I LOVE this keypad. It looks great and it feels great. It's super solid, I love the metal outside, and the switches are nice and creamy. That said, getting this thing up and running was an absolute PAIN! Out of the box, it worked fine when hardwired via USB, but I could NOT get any of the wireless features to work. The signal would constantly drop, the input would lag, and keystrokes would be lost. I ended up spending 4 days going back and forth with Epomaker support (since I'm pretty sure they're in China, I'd get responses overnight) trying to resolve my problems. I will say, I was able to resolve my issues, but it is found NOWHERE in the keypad's documentation, nor on Epomaker's website, so I'll list the troubleshooting steps here. Wireless Connection - Turns out, there is a known issue with USB 3.0 and 2.4ghz wireless. Due to the frequency used in USB 3.0 communication, it can interfere significantly with 2.4ghz signals. If you're having issues, try plugging the wireless adapter into a USB 2.0 port. Unfortunately for me, my computer doesn't have any USB 2.0 ports, which is likely why I was having problems I couldn't resolve on my own! I did discover that if I plugged the wireless adapter into a USB hub, the wireless signal worked flawlessly! This is also a known solution to this problem. I'm glad I was able to get it working, but I wish this information was provided in the included documentation. Also, I have a couple other 2.4ghz peripherals, and all of them work fine on the USB 3.0 ports. So although this is a known issue with USB 3.0, it seems other manufacturers have been able to resolve this issue, why can't Epomaker? Software - For such an expensive keypad, it's really disappointing that it relies on open source software, (which needs to be downloaded from github...) in order to operate and modify its settings. Since Epomaker doesn't control the software, their included documentation does not properly reflect the latest release of the software nor how to operate it! At the least, I would expect they would update their documentation online, but alas, I had to spend 4 days with tech support in order to get it working. For starters, you have to download a JSON file to make the keypad compatible with the software. The link provided in the documentation is no longer valid, so you need to be pretty good with your Google Fu to download the right file and avoid scam links. But even once you get the JSON file, since the documentation hasn't been updated, it's not clear how to use it! To get it to work you have to go to settings and select "Enable Design Tab." Go to the design tab, (I believe I also had to enable "Use V2 Definitions (Depricated)" because, again, Epomaker hasn't updated their software or documentation, then you can FINALLY load the JSON file to get the keyboard working in VIA. I really wouldn't mind any of this if Epomaker just kept their documentation up to date! They don't even need to include paper instructions, they could just include a link or QR code to a website which they can constantly maintain and update as things change with the appropriate steps and valid links. Clearly tech support is aware of the issues and is able to help their customers, but customers should be able to figure these things out on their own. I can't imagine how many returns they get because of this. I also really don't like that the keypad relies on open source third party software which can change at a moments notice, which can instantly break the functionality of the keypad. I really hope Epomaker is helping to support the developer since they're using their app. All in all, great keypad, but hate that it took me nearly a week to get it properly up and running...
