Input:
This is the second set of bands I ordered from Black Mountain Products.  I'm still using the first to replace a set from another manufacturer that dangerously separated and snapped off between the handle and the strap after only six months.

This second order is for my personal trainer who liked them so much that he is now using it with his other clients!

The reason:  they are made with high quality rubber, and in the design were manufactured to guard against dangerous high tension breakage.  With this set, you can customize the tensions and combine them to get as tough a workout as you could possibly want without ever going to the gym.

There is an included instruction booklet included, which makes understanding how to get the maximum benefit from exercise.

Whether on the go or at home, this is the only exercise band set I will ever use.

Lastly:  customer service.  You can speak to the owners of this business who really care about their products and will go the extra mile to personally assist you in explaining what you might need, or if you have a question.  I haven't reached the need to call with a problem because in almost a year, I've had none.

HIGHLY RECOMMENDED!
