Good price and good quality. I've only used the yellow and orange so far but so far so good and I've had no issues.

These bands are sturdy and great for home workouts.

When I first started using these bands, I used just the red one. It worked great for helping me do chin ups. I then wanted to use the blue one. When I opened the blue one, it was stuck together in multiple places, such that the rubber was tearing. I contacted customer service and they immediately sent out a new one. They did ask me about how I had stored them, but they sent out the new one before I had answered their questions. I've now checked all of them, and the blue one was the only one affected. I'm using the green, blue, and red ones for multiple exercises, and might start using the smaller ones soon. I love having the variety so I can grow into, or out of, them as I get better. Thank you so very much, WIKDAY for a great product and for excellent customer service!
