Number Pad, Mechanical USB Wired Numeric Keypad with Blue LED Backlit 21 Key Mini Numpad for Laptop Desktop Computer PC Black

The lights could use some more functionality, and I wish I could change them to one color (but you can turn them off), but the tactile feel of the keyboard is AWESOME. I love that it has a backspace key as well so I don’t have to break my 10-key stroke. I like the klick-knack sound of the keys, but if you don’t then you should know that the sound is pronounced. It works with a PC or a Mac. I rate this one highly.

Works good

works great

The most important button on the device is the "Bluetooth code button". It is the small button next to the on/off switch on the back of the keypad. This button puts the keypad into the discoverable mode. Press Fn + BT1 or BT2, then after the blue light goes out, press the small button and the blue light will flash to indicate the pairing mode is active. This was the one button not translated on the instructions.

Has trouble maintaining Bluetooth connections with a Chromebook laptop. Happen so frequently that decided to go with WiFi plug instead

This kind of works but you have to be very intentional and firm with each key press. If you are trying to quickly punch in a string of numbers it doesn't register half of the keys you press, which as you can imagine is very annoying.

The device decides when it wants to connect even while plugged in. Have yet to be able to use it as a Bluetooth device. Today it disconnected, it's plugged into the computer, and will not reconnect

Those are NOT programmable RGB LEDs. The color pattern you see in the pictures is the only one you will get. Only the blinking pattern and brightness are adjustable. I was hoping to make it match the color of my keyboard but now I'll just leave the LEDs off because that default color pattern looks terrible. Functionally, the keypad works just fine so it is deserving of something in the score. However, given that the product is designed and advertised in such a misleading way, I can't bring myself to give it anything but a terrible score. Seriously, I would have paid an extra 5 bucks for this product to have true programmable RGB LEDs. Update: The device doesn't even remember the LED settings you have previously selected after being turned off and returns to the default ugly fake RGB rainbow settings every time you turn it back on. I have returned it. This is disappointing, because making it work properly the way it should have wouldn't have made it that much more expensive to produce. I have returned it.
