Input:
I purchased the bands to use for p90x back in January. I'm a petite 5'2" female, so I haven't had any issue with the bands being too short. Usually I work out at the gym but this year with my tight schedule and how much more expensive free weights are, I thought I'd try out these bands. The bands have been working great so far and serve their purpose for the most part.

Pros
-durable
-affordable
-the carrying case is handy for organizing/travel
-good grips
-door anchor is nifty
-nice alternative for free weights
-called customer service for a question, there was no machine/menu in the way and they picked up quickly. Person I spoke to was helpful.

Cons
-limited instructions: At first I didn't know what the door anchor was or how to use it since I forgot it came with the set. (On the other hand the fact that they cut down on packaging clutter is nice too and I figured it out eventually after giving it some thought.)
-only one set of handles: For p90x, I alternate between band strengths and sometimes it's difficult to keep re-clipping and switching bands between sets. I plan on purchasing another set of handles when I can fit it into my budget.
-For some of the exercises, where you have to loop the band and step on it with your weight to shorten and increase resistance, since I'm petite, I've had some difficulty utilizing the bands properly. This isn't a complaint of Black Mountain but for bands in general since this would not be an issue with free weights. Nonetheless, I make it work one way or another.

Overall, I'd buy the product again and have not regretted the purchase.
