First of all they price is very good. Turns out it is too good to be true.
The first time you apply the brakes in the morning they will squeal. When braking normally you will hear some rumbling. Under moderate braking they will make a lot of rumbling noise. Their email support is kind and upbeat but cannot do anything for you to provide actual support. I don't drive the car a lot so I thought I'd give it some time to see if things improved. It got worst over the following months. When I called to talk to them the level of support was not great-- it was only RMA dispensing support, not actual technical support. I was looking for someone who could tell me if this is normal and would really know what they were talking about. Since several months had passed by since the purchase (my mistake), they said I just needed to get new ones to see if that solved the problem. I will be doing that eventually-- but will pay the price for a brand name.
