Significant criticism of the set is the lack of attachment. The front light bracket is not firmly mounted with a screw on the frame, but only engaged by pressure. This may provide a stable hold at relatively comfortable ride. However, on rough roads or speed bumps shaking the lamp and occasionally needs to be readjusted. Even worse, however, is the taillight mounting. Here the bracket is to be fixed merely by elastic band around the seat post. In my few days has kept then gave the (too thin) plastic hook of the rubber mount for the lamp and fell off. Positives: the fall it survived with only minor scratches. After another failed attempt with superglue I have now wrapped the lamp with "beautiful", but strong fabric tape around the seat post. This keeps.
Conclusion:
Because the luminosity for that price there were 5 star, but 2 star deduction for incorrect mounting
