I've never heard of them either, and after reading your post I tried to dig around and found nothing. In my opinion, looking at their site and their prices something just doesn't feel right. When you're selling refurbished vokey's for less than $25....it just doesn't seem right. I prefer to follow the saying that if it looks to good to be true...it probably is.
Even though I couldn't find anything negative about them, I also couldn't find anything positive. If they were a successful site like 3balls or 2ndswing, you'd probably have a lot more people talking about it. Just my 2 cents! Best of luck!
