I have had great Luck with them. when I had a Problem with a Night rider set up , and sent it back , they actually called me back to offer me a Refund ( which was against the policy ) I was very impressed.
Usually they're the cheapest online mailorder shop out there...always ship fast, never a problem. A lot of their stuff IS OEM/older stuff...if it sounds too good to be true and you're hoping for 07 stuff/retail, it probably is.
I don't mind PP. I'm not a big fan of OEM stuff, unless I know that's what I'm ordering and the price clearly reflects it. I had a problem with a heart rate monitor from PP and they were nice enough to pay return shipping etc. I won't buy Sette products, but the rest of their stuff is fine and their shipping is much faster than Nashbars!
