I think I've had the pro clip for a couple years. I didn't think to try and return it, but it has to be way out of warranty.
For me, it works better than the reflector clips. I think a lot depends on the lighting in your room. The reflector clips worked fine at certain times of day, dont remember if it was night or day, but they didn't work very well the rest of the time. Especially on the "edges" (extreme to right or left, for example), the pro seems to work better. For me.
But it really is a piece of junk, manufacturing/design wise.
They said they couldn't find out the problem, because in their in-house testing, it always performed great. They finally figured it out when they realized the plastic was getting brittle due to shipping or transshipment or something, because they were left in the cold. They say they changed the plastic formula, and maybe also added some strength ridges, and now it's tougher.
Mine still mostly works fine, but I think I will build in a strut to keep it at the right angle off my head.
