Bests & Worsts Reviews from Amazon

These are all based on a simple idea of using the elasticity of bands to provide resistance for a workout. They only needed to do one thing to improve this basic idea so that it could be safe to use at home. The resilience of the elastic bands. However, these are just off the shelf bands with no improvement. As a result, these bands easily rip and tear after a few months of use. The lifetime product warranty that they are talking about covers only the first 90 days of use because that's how they define the product lifetime in the fine print. That's the product you will be paying $30 for. Beware.
