Great product. I give 4 points because the material doesn't forgive crass things. It comes off easily and has no end point so my screw went all the way through without me noticing. The screw wasn't sharp or anything, it just went all the way through the hole and started pushing the grip tape up from the inside. I was able to fix it fairly easily but the screws aren't tightening so I attached it to the battery and it spins. It's larger than I thought it would be, but in fact the clamp is strong and tight. I would buy another one just knowing I would have to use some kind of glue to fix the turning problem.
