They sent me non-working LED's and refuse to honor them. They are acting like I'm trying to scam them for a $3 led when I spent $40 and only two did not work. They are slow walking the return and have been asking me to take various pictures of the non-working LED all week and then they state they cannot do a return unless I can prove it's broken by showing physical damage in a picture, but I can't and they know this. Be careful with this company because the buck you save now will be lost when the product arrives. Go with a reputable company that stands by their product.
