In late December 2015 or early January 2016 I bought a Powertap Amp G3 35/35 wheelset from them. They eBay ad said "raced 1 season." I still have those wheels and aftet 5000+ miles the brake track is just starting to show the slightest bit of wear.
The wheels were around $2200 new, I got 'em for $1000 at the time. The front hub is just starting to make the slightest audible bearing noise but spins true & long.
I wouldn't hesitate to buy from them again. They were new as far as I could tell.
