Track is great and rollers work really well - I'm just so upset that they do not include nearly enough roller/hooks for the size of the track.  EVERY has commented on this.  It should include 5 more roller/hooks for a small, 10 more for a medium, etc.
I makes no sense!
It comes with a saw to cut the track, which is great, but I'd rather have the roller/hookes I need.
