All of my prior experience has been on either Scubapro or Atomic regs, and I must admit, the Hog D1 breathes just as easy (maybe better) than regs that cost double what the entire D1 package costs. It is easy to adjust underwater to make it breath exactly how I want, and everything is large enough to be adjusted while wearing gloves. The only complaint that I have is that, with hoses attached, the swivel action is limited by th DIN wheel. However, this is only a minor inconvenience and appears to have been corrected with the new D3. Highly recommend this reg, both for quality and value!
