Ours is better because

 

 Tube supports… part of the frame, to keep the weight off the expanded metal.
Years later, our first ScooterHitches are still in great shape.
 

 All three wheels on a 3 wheel scooter, all 6 wheels on a powerchair are supported.

 
   

 Our carrier has a six inch tall guardrail… if you forget the hold-down strap, your scooter is still safe, can't bounce out.
