I've been keeping an eye on the Shuffletech shuffler for a while. It was announced months ago and seemed to be taking the route of vaporware with repeated "almost there" updates. Well units have finally shipped and I've been following the reviews on the HPT and 2+2 forums. The news has been good from a functionality standpoint, reasonably fast, effective, can de-jam itself unlike ShuffleMasters. Biggest knock on it seems to be the noise. It is not silent like the casino shufflers though it is hard to tell exactly how loud it is.
Here's a video of the machine in action. Speed of an auto-shuffler is always going to be slower than a decent manual shuffler but it is not going to be a holdup for a full table cash game. Looks like it takes about 60 seconds for a cycle and you are not going to find a ring game getting in 60 hands/hour.
Anyway, I'm going to continue monitoring the threads to get more feedback on these units. If these things are all they are advertised to be then we can expect to see a trial run at our game.
