First with their eye-watering prices compared to other pedals.
Second, some of the total junk quality products - just check out some reviews on on MTBR on MXR and Smartys.
Now, having just received a set of new SL pedals, and noticing that they have downgraded the spec of the SL - no longer SS spindle but chromoly. SS spindle was one of the main reasons for getting SLs - I don't want to baby the spindle after every wet ride to prevent rust, because I have lost a Candy C to rust this way - not babying it after every wet ride.
PLUS they have included a set of small cleats, not even the premium cleats. They are even smaller and junky-er looking than the original cleats, without any side wing.
