Review on Maxsa 37353 Park Right Tire Saver Ramps: Effective Flat Spot Prevention & Vehicle Storage (Set of 4), Black by Mike Bigglesworth

I bought these for our Corvette as we are not home all the time. I sent them to my wife at home. She tried going straight on it, backwards on it, etc. Every time the front slipped, the back then slipped. She said she couldn't drive to them. There is some rubber underneath, but apparently not enough. I sent them back but maybe I'll try them again in the future, maybe try to find rubber pads to put them underneath. We just covered the floor with epoxy which probably has to do with that. So if you have smooth floors, brace yourself for a challenge.
