Review: Great product for quick switching Samsung and Windows - Initially I was skeptical about getting a keyboard without a rechargeable battery but this keyboard is great. Very high build quality, great range and it works with all my devices flawlessly. I simply use the rechargeable cells from desertcart and the batteries last months for me.
Review: It's affordable, but is it worth the bag space? - This keyboard is ultra-thin and lightweight. The connectivity, between devices at that (including non-Samsung), is excellent. If you need an affordable travel keyboard, this will work. Battery life is great. It takes two AAA batteries. +Downsides: 1) No 2.4 Ghz connectivity (BT only) 2) No backlight 3) Poor keys quality +Considerations: Some keys may not function normally with some devices (specifically function keys like Dex button).
