It is easy to type faster than a lot of keyboards. It has tactile feedback without being too much. It can be used with up to three different devices, although I haven't tested that. The mouse has a nice feature that you can turn on and off the ratcheting of the scroll wheel.
I've needed a mid-sized Bluetooth keyboard for use with my old iPad. Apple no longer makes one: what's available are keyboard-case combinations, and my tablet's too thick. I've tried several Bluetooth keyboards: none would pair up. This pairs instantly. Nice size: big enough for large male fingers; small enough to take with me. Uses two AAA batteries that probably last forever. And it's cheap.
Works straight out of the box. Very cool switch options. Great build quality for price.
My reservations were twofold. The price was a bit expensive, and I was unsure about it's ability to enter a computer's BIOS. I have been using a variety of keyboards since the mid 80's, and this one is the easiest to use with relatively quiet keys, unlike other mechanical keyboards, and I can get into the BIOS on my three desktops with ease. And once using it, I haven't thought about the price at all.
both devices use the same USB adapter or bluetooth
