Well, I had an issue with these. I kept getting the blue screen, but the seller has agreed to send me another set for a charge and we will see what goes from there, but the seller did not even question it.

Item received fast, however I had an issue with one of the modules, but seller quickly worked with me to solve the problem, good communication, so for me it is a very fine seller A+.
