Works good overall. I noticed a few dings and scratched off paint marks on the spoiler on the topside, but it wasnt bad enough for me to want to go through a refund. The underneath (where the tape is applied) had about 3 drill holes that werent cleaned up, so i had to sand them down. There also were no instructions and not enough 3m tape, i had to go buy more from the auto shop (i recommend doing that anyway, get the wider heavy duty 3m tape). Love how it looks despite all the fix-its!
