These carriers to the proverb confirms: "Those who buy cheap, buy twice"
After two years of leave use it begins here and there to rust (although rarely in use on the roof). In addition, the plastic comes off the lock. For two years, it was ok - but now we have to buy it again. Assembly was also very inconvenient (reminded me more of a metal construction) and also the bikes wobble heavily on the roof.
Since I was able to use the carrier at least for two years, there are 2 stars.
