This is a very well designed system. The handles clip on and off the bands easily. The bands have been sturdy and function every bit as good as any I have seen and/or used in the past 25 years. The design for the strap that jambs into the door to anchor the setup is well designed. I did have a problem with the balls that are sewn into the anchor end breaking. Having used other setups with an anchor strap I am not sure why this one had a bit of a malfunction. Even flattened though it is still anchoring. That is why I didn't give it 5 stars because of the anchor strap.
