When I was looking for a bike rack, I didn't care about for price honestly what are the difference between the cheap and expensive ones. What really bothered me is there is an actual risk of my bike falling off. I read lots of reviews and feedback. If anyone looking for a bike rack, I found mine here.
If some one worring about instalation. So long as you are strong enough to get a bike up to the roof level, it can by loaded without assistance: just get the bike in place, hold it with one hand while tightening the clamp with the other then tighten the straps holding the wheels and the job is done, with the bikes rock solid.
Hope this is helpful
