It uses two AAA batteries. The keyboard is very easy to pair with your devices. It does not drop very often, but when it does, it reconnects rather quickly. It is built slightly tilted. It has a nice finish that is a mono shiny look. It sits easily in my lap or on a table. The overall quality is very good.
I am typing this review with it. It types with no noticeable lag, the buttons are very smooth and it is very slim. It will fit easily into a briefcase or backpack. I used it on my Home Theater, Laptop, and Tablet and even on my Galaxy Note 3, just for the heck of it. It paired with them all quickly and worked flawlessly on all.
The only drawback that I had is that it has no light indicating caps lock is on.
My conclusion is that for the price and if you are looking for something to make your typing life easier, then I highly recommend this for you. Give it a go!
