To be honest I was very nervouse about buying an item with no reviews but I am proud be the first to do so because this keyboard is amazing my laptop was normal keyboard and I wanted the back lite one and there wasall these expensive ones and this on was inexpensive and has been working great!!! I am so glad I baught this and the keyboard dims down when your not using it which saves battery!! I would buy this item in a heart beat over again and probably will for my friends laptop too!!!

Faultless and make sure if you are comparing this to others that others are also backlit.Helpful video showing how to replace the keyboard (very simple) http://youtu.be/8yY3j8ifvB8
