So far I love the shuffler. I have noticed that some decks tend to cause jams (or if they don't jam, the shuffler seems to struggle a bit with them). I tried it with several different brands and decks ( I have 12 different decks) and my initial theory is that the shuffletech struggles with heavier decks. For example, the Desjgn cards I had with the red/blue back caused almost all the jams, whereas other desjgn cards, davinci, copags, etc. did not. Here's a picture of 2 different Desjgn decks of mine--the top one struggles and/or jams while bottom deck shuffles super smooth with no issues.Let us know how you like using the shuffler in gameplay
I'm guessing the top one is a different card stock than the bottom. The top one also has a more linen-like feel whereas the bottom one is more smooth.
