EcarkeMini 4-Key OSU Keypad Hotswap One Handed Keypad Mechanical Gaming Keyboard,Can Self Programming Macro,with 1.5m USB-C Data Cable（Upgrade Cherry Shaft & RGB LED

I purchased this for gaming, specifically for additional cockpit buttons for my flight simulator.OVERVIEW:This is a well-made, solid, little keypad with a quality feel to it. The blank white keycaps can be easily replaced if you so desire. I just used some label tape to label mine.Switches are a bit on the soft side, as compared to my Cherry MX Browns in my regular keyboard, but that's not a deal breaker for me. They are just not real "clicky," if you're expecting that.I particularly liked the horizontal layout; it is perfect for my intended purpose. The face is glossy white with a clear base. There are 4 non-skip rubber pads on the bottom. There are no lights.The unit measures about 4" x 1" x 1" approximately. The data cable attaches to the long side, which by default is on the top right. I turned mine upside down so the USB cable came out the bottom left, then took off the keycaps and turned those upside down as well.The included 1.5 meter cable is long enough to reach most desks to PCs. It's a flat ribbon, not round cable. It's USB to micro-USB.PROGRAMMING:Download the programming software from: https://osu.sayobot.cn/download/Tip: If you want, you can run this site thru "Google Translate" to see the English version of the page, or just click the big green button to download. The program itself can be switched to English in the menu.The programming software is visually intuitive and easy to use. You can make your 5 keys do anything you like, including single keystrokes and keystroke combinations (macros).Note: When I first attempted to use this programming software, it told me "Device not connected" even though I could type "1 2 3 4 5" in Notepad as the default keys. This was because my existing 104-key macro keyboard was interfering. So I plugged it into my laptop (which does not have a programmable keyboard) to program it.Macros/programmed keys are saved right on the unit, so once done, I re-plugged it back into my desktop. There is NO CONFLICT once programmed; I can use it and my regular keyboard at the same time. However, I will need to disconnect it and use my laptop again, if I ever want to change my macros/programmed keys.CONCLUSION:This quality little 5-key keypad adds 5 macro functions and/or personalized keys to any computer. It may have its programming quirks (as noted in this review), but if you are in need of something like this, I highly recommend it.

I received a defective product, randomly disconnected, hard to use. It's easily moved, even with the bottom padding, on a desk mat/mouse pad (perhaps if there were some kind of extra weight this could be avoided?). The shafts are a bit "loose" to hold the keycaps, so there is some wobble (maybe this is intentional?).This had high potential, but the product quality is EXTREMELY DISAPPOINTING, especially since these 4 keys costed about 25% of my hot-swap tri-mode TKL. Still usable, but definitely considering a return.(In case you're worried, the software is NOT spyware/malware.)

I purchased to use at work. Do a lot of copy , paste for emails, ads and posts. Figured for $17, I’d try. Setup was easy, but would be hard if you’re not very novice with basic webpage setup. Asian webpage, in English but not really set up to help you set this device up. But had it configured in a couple minutes. Works very well, definitely saves time when sending out multiple messages. Would recommend. My manager will be getting one too!

I use a graphics tablet for artwork and I can move my keyboard out of the way with these three keys programmed to Alt, Ctrl, Shift

Embarrassingly struggled at first to figure out how to connect the keypad to my laptop and make changes via the browser. Once I did that, the rest was super easy. I use this for music controls. Left is previous track, middle is play/pause, and right is next track. Love it
