Logitech's black K480 Bluetooth keyboard is capable of connecting with up to three devices simultaneously, and right now Amazon has it available for just $19.99. This price matches a deal we saw in August and is almost $10 off the already inexpensive keyboard.

The compact keyboard works with Bluetooth devices universally and has the ability to connect and switch between up to three devices. With that feature, you can easily fly between using the keyboard with a tablet to using it with your phone and then back again. It can connect to devices up to 33 feet away and also features an integrated cradle which can hold a phone or tablet in front of you while you're typing.

It's compatible with Windows and Mac computers, along with Android and iOS devices. You could connect it to a Chromebook, too. Logitech includes a one-year warranty with its purchase. At Amazon, over 2,200 customers reviewed this keyboard resulting in a rating of 3.9 out of 5 stars.
