I use the pedals now for over 3 years on a regular basis on my cross bike and have to say that they are very robust and I am very pleased overall.
Recently a pedal but has begun once per revolution to crack under light pressure. As you can read in some forums that is probably more common and sometimes can not be so easily leave. For me, however, a little oil has been sufficient to the camp, then there was nothing to hear.
The focus of the pedals does not lie on the axis of rotation, but on the side of the normal platform. This means that they automatically rotate so that the click-side up.
But to assess the remains entirely up!
