Vaydeer 4 Fully Programmable Keys with Floating Window and Macro Multifunctional Keypad, One-Handed Mechanical Keyboard Support NKRO, Hotkeys, One-Click Start, Compatible with iOS,Windows

It works good. You just have to figure out the software which is not intuitive. I plan on buying another one

This falls into the, "I can't believe someone actually makes this, and it's perfect" category.I keep music playing in the background on a second computer at my desk during the day, but when someone calls I need to quickly pause it. Enter the Vaydeer 4-key keypad. One button to play/pause, another to play next. Another will awake the computer and... one to spare! Attaches easily to a command strip to stick to my desk. Handy gadget, can't believe I found it, and it works as advertised.

This item is fine in theory but it doesn’t work as advertised even have programming for my my needs so I’m returning

The build quality of the switch is excellent, but the software seems huge for such a simple device. The website to download the software was a bit confusing because I don't read Chinese, but after a few tries it did download and install. Once installed programming was simple, and it did work nicely for my needs but...I did return it because there is no way to turn off the on screen display, which defaults to the lower right side of the screen. It is possible to drag it off enough to hide most of it, but it serves no purpose other than to let you know it's active.

This is actually the third one of these great little keyboards I have bought for day trading. I bought this as a "used" item to save a few dollars unfortunately the previous buyer that returned the keyboard kept the USB cable. I contacted the seller and they went "above & beyond" to correct the missing cable. Great communication and timely fix.

Great software will buy again

Does not work for Mac. OS is outdated.

Programmed it on a pc for some simple key substitutions. Tested with notepad and it works. Unplugged it from the pc and plugged it into my Mac. The Mac did not recognize it. The floating window, complained about by another reviewer, is annoying.
