These machines reliability seems to be questionable. At Harvey's I regularly see the machines having some sort of problem. At various times I've seen:
1) extended shuffle times (minutes)
2) incorrectly identifying short decks (red light says short, hand count
says otherwise)
3) jams
4) power offs (independent of the power cord getting kicked out)
#2 was happening often enough for a while that some of the dealers would
just ignore the light
