Yeah, I have a couple videos by this company. If I can find them (big if) I'll post a review. I've never been that impressed despite the seriously hot women. They tend to be poor sellers of the material (think fitnessactionwrestling). Darrius is in a lot of their videos, and he also seems like he should be much better as a performer. As the clips above indicate, he is really obviously pulling his punches or swinging at the air. In one of the videos I own, the performers are strangely wearing flip flops.
To give them a little benefit of the doubt, in my opinion pro style boxing is more difficult to simulate than pro style wrestling. For one thing, the entire visual vocabulary of pro wrestling has been honed over many years to look more or less convincing. In boxing, if you don't film it from the right angle, it either ends up looking terrible or weak. This means you're always looking over the shoulder of one of the performers.
