Rack works well for 2 adult bikes. I have never tried 3 as I do not want to put too much weight on the tires support. I recommend removing the spare tire cover when installing the rack. Otherwise you would be scratching it. Even my nylon cover was eventually removed since it was rubbing on the rim lip.
I also had to slightly bend one of the arms as it might have rubbed against the rear wiper when it operates.
The Thule is definitely better built and more secure. I used it everyday for 4 months and drove on the highway 2-3 miles at 70 mph everyday with no issue though.
