Input:
Bought to be able to mount kids bikes (12" boys frame & 16" girls frame) on Thule hitch bike rack.  Worked well.  From my research, adjusted to a smaller length than most other adapters, and that was critical for my use.  Worked well, held bikes steady.  Seems fairly robust and well made.  Easy operation of adjusting length and push button for opening clamp.
