Going to see how cool these things are to own. We went to an event called Beat Me In St. Louis a few years back and they had something like this there. They even gave a class on how to use them properly. They allowed for demonstrations and volunteers. It was pretty cool to use and to have them used on you. This set came in a metal carry case and looks to be pretty nice. The one they had at the show was very nice and I am sure it was an entirely different level as this one we just got. We will provide some updates on the experience as we use it and learn more about it's use.
They're a lot of fun 
Very nice! We've wanted to explore those for some time, do you mind providing a link to the exact set you purchased?
Here is the link to the one we purchased. I tried to do some good research on them. They have antique ones that are very strong and very pricey. Then there are cheap ones that have so many mixed reviews that it was hard to make a good decision on. This one seemed pretty nice, middle of the road type unit that had all the basics with the ability to add other attachments as you want later down the road. The price was the best price we could find for a set like this. Hope that helps. Since we just got it maybe we can all get together and try it out if you are interested. Maybe we need to start a group and everyone can learn together. Would be a fun way to meet people.
