Input:
Ordered the Black Mountain set of five bands, because I did not want to have to buy additional bands separately, if needed.  Plus, I like having the door anchor and ankle strap, too.

Quality product, the straps are strong, stitched well, and not flimsy, so it seems it should last a long time.  The door anchor is also very strong and put together well.

The bands come in a range of resistances from 2-4 pounds, to 25-20 pounds, plus you can combine the straps to produce upwards of 50-62 pounds of resistance.  ( Resistance measurements based on supplied documentation )

Their customer service is knowledgeable and helpful.  This was my first time using bands, so I just wanted to ask about what to expect, care for the product, and anything else that would be useful.

The straps do what they are supposed to do and I am happy with the purchase.
