This small keyboard at the base is intended especially for Iphone or Ipad works great with other equipment; I tested it on an iPhone but also an Asus branded tablet from Samsung and another brand, it works fine. There are just some problems with some signs on the keyboard that does not respond but nothing serious. In use, this keyboard is very nice and very convenient. It is super light, thin and easy to carry. The material is pleasant to the touch, flexible, much like the fabric. The duration of the charge is announced three months to do with the time. It can be handy for people who have a lot of text to type on their tablet for example. I removed one star because I think its a bit expensive anyway.
