max.1 star! and then only because of the quick installation! Otherwise processed very cheap and never thought for 3 wheels! Yesterday was the first time so go 2 adults. And a child's bike! On the way back, the side bracket has forced apart the frame as far as the 45 were in the wheels degree angle to the road. Say the material is cheap trumpet sheet and me it is a mystery this model has the authorization. Unfortunately have already disposed of the box or I would send back the waste. Now I try a locksmith to find a solution which is in the Drive gets no sweats. And the belts for the wheels do not even have endured the outward journey. Possessions me but safe side had already packed bungee cords.
