This product will function using a Poker sized deck of cards or cards stating a size of 3.5”H x 2.5”W. Bridge sized cards are 3.5”H x 2.25” W, which are slightly narrow, and could work in this unit. In regards to the comparison of this unit and a ‘manual’ unit, the only difference is the pressing of a button vs. shuffling by hand.
Sometimes in shipping the gears of the shuffler slip out of alignment and need to be adjusted. Make sure all gears are touching and this can be don e by simply sliding the gear back in place
