Not yet, but a buddy got one for Christmas and loves it. He showed it to me and it looks great, seeems easy to use, and is built like a tank compared to other (cheaper) throwers. If it works as well as everybody says, I'll be ordering one soon too. Let us know what you think when it comes.
I have had one for a while. I have found it to work great, no problems at all. I wish it would throw at a little higher angle but that is not a major problem. I would buy it again.
