Jan Rouven was great! I was a bit worried about what to expect since it was a show off the strip, but I would definitely recommend to friends and family. He is a bit more personal with the audience (looks for audience members to participate) which I think is great.
The only thing I found a little cheesy was him trying to sell his magic kit at the end of the show. I suppose that's how upcoming magicians start out? Regardless, after the show he met everyone in the front entry way to "autograph" entry tickets or anything else which is very personable and warm.
Go see him. Skip David Copperfield. I honestly hope he makes it big in Vegas. He's charming, handsome, funny, and very down to earth. He's certainly a rising star.
