Picked one up recently, and slowly getting used to it.
You can fold the legs backwards and then deploy them without pressing any buttons or pulling - just shove forward and they'll lock into the 90. Downside is that you can only do that with the legs stowed backwards (or else your tilt knob faces downrange).
Legs are just a hair too easy to extend for my taste. The button to fold them back up is a bit too small, for that matter.
Not having a TBAC, Accu-Tak, or Cyke to compare them to, it's hard to judge. I'd guess they're still noticeably better bipods, but overall I've been happy with this one so far at half the price.
