Bests & Worsts Reviews from Amazon

As a safety issue I give these 1 star. I bought these because they're described as double-locking (ie safe) but the saddle bar teeth barely extend over the lock bar. It's like 1/32" of coverage on one end and 1/16" on the other end. I think either the quality control is poor or they're a design clone and they didn't know how important lock alignment was when they cloned it. Another possibility is that they correctly designed the stand mouth BUT for a saddle bar that had wider teeth, not what was included. What I got is totally unacceptable from a safety standpoint. I'll be returning.
