There are indeed partly a little different versions (metal lead) also here at Amazon, these reflectors, but in principle they are all processed equally. Considering the screws too tightly, it pulls the thread out of the plastic body and is therefore broken. Taking into it when installing the pedals to work, everything was perfect.
The luminous efficiency of the reflectors is good and contributes a little more to the security to be in the dark or at night seen better. The cultivation is somewhat tricky because you barely have to screw clearance. Here you should buy a small open end wrench of clearly comes within the narrow body of the pedals. In a pinch, it also does a flat pliers.
