### ⭐⭐⭐ Review
*by G***W on 31 October 2021*

Firstly, what I like. The product is obviously build to last. The feel is good when I’m typing with it. It’s compact but includes the four important keys, page up, page down, home and end. Then what I don’t like. I would give it a five star if not for the short battery life. The keyboard can only last one week even though I turn off the backlit because I have no use of that function. I can live with that by charging it whenever I remember but it’s really annoying to have yet another device to charge frequently.
