I just bought one of these, tried it out, and it works pretty well. I thought I would pass this info on to anyone interested in purchasing one. I wanted a FA vibra prime, but couldnt find one anywhere, and didnt want to spend 300 bucks on Dillons model. Here is a youtube link showing how it works, and the info on how to order one is in the comment section below the video. I payed the guy through PayPal on Monday, and had it on my door step on Friday.
