The light angel did not work at all. 2 of the 4 sensor lights would not work in the auto mode.
I called them and they sent replacements right away. I was very happy with their customer service. My only complaint was that they have a disconnect between their customer service department and their billing department. One tells you don't pay until you receive your replacement and the other bills you telling you that your over due and will be charged late charges.
I will say this, how many places even send your purchases out before you pay them now a days. In general, I am very happy with their customer service and the way they treated me.
