Stating, “Best Bluetooth Multi-Device Keyboard Out There” is my personal opinion; HOWEVER, I will tell you that the Logitech K380 Multi-Device Bluetooth Keyboard is, by far, the best bluetooth keyboard I have ever owned. I have tried quite a few bluetooth keyboards and my experience with them have not been good. I would often experience lag time when typing and disconnects from the device I was using.
The Logitech K380 changes all of that: but, the main feature of this keyboard is that you can connect up to three devices to the keyboard and toggle between the three on the fly. For example, I connected my Minix NEO Z83-4 Mini PC, my Samsung Galaxy Tab S, and my smartphone to this keyboard. Toggling between the three is a simple as 1-2-3 (number’s individually assigned to each device). I cannot get over how fluid this keyboard is. As a matter of fact, I am composing this article using this keyboard; AND, even though it is a mini keyboard, I would not hesitate in using it as my main keyboard. Another biggie with this bluetooth keyboard is that it takes two AAA batteries and according to Logitech the keyboard will give you 2 years of use between battery changes. The keyboard is available in four different colors.
As of this posting of this article, Amazon has the Logitech K380 on sale for around $30… Normally it is priced at $39.99… In my opinion, this price is reasonable, due to the fact that you have the option of connecting to 3 different bluetooth devices and that it is very reliable for a bluetooth keyboard.
