I've been running it's predecessor for the last five years now and love it. The 201 was designed for beefier rifles like the TAC-50 and ASW50, where a simple Harris or Altas might not cut it. On larger rifles, I like bipods that are mounted above or near the bore center line for added stability, and having had bipods from RND for our .408 Windrunners, Troy Vanvaley and I asked Lloyd to make a version that we could mount to the side rails of our new SRSs back in 2009.
The main complaint I've heard from people is "it looks like it doesn't swivel!", which is true. Though for me personally, the goal was stability over anything else and when you're shooting ELR distances, there's less of a need to swivel along Y or Z axis. Is it pricey? Yes. Is it solid? Very. In the five years I've had mine, they've taken quite a beating and held up very well.
Would I use it on a short action? Nope, but they're great for that area where the average bipod seems a bit under-supportive.
ETA: I like this bipod so much that when I finally get around to an HTI, I'll be getting a set of 201s for it.
