This arrived without any of the power adapters making it completely useless.
I did slip it onto my seat to at least review it for fit, comfort etc...
It failed that department too!
When you get into your vehicle and sit, the cover slides with you. It slides down the back of the seat as well.
Does not stay in place, I don't see how even if I did get the adapters with it, that this would be of any use at all.
