I've used it. No problems at all. They set me up with their guy at a store that I buy from all the time anyway. It was a smooth transaction. Same guarantee and return policy as with any purchase, they just don't include the "$150 of free extras" advertised on the website, like the cheap tripod and undersized camera bag. I will use CPW every lens and camera purchase from now on. I had no concerns about return policies, and they told me exactly what is was getting before I handed over payment. In my case, completely new in box, US warranty, no lens removed or anything.
