I have one of these Saris trunk racks and have been using it for about a year with out any real problems. I did get some little foam pads from the hardware store that have a sticky backing and put them on the straps to help protect the paint on the bikes. I have notices some light rub marks where the straps go on the frame but I use this rack every time I ride so the bike must have been on and off of there 100 times by now. I am thinking of getting a hitch rack soon as much as I use this thing.
