It works well for the price paid. It's a little tricky to figure out the correct amount of coins in the tube. We just pulled out a kitchen scale, counted out the correct amount of each coin for the wrapper, then weighed it to create a baseline for each type of coin. Fromt here it was pretty simple to check the weight of each coin wrapper and add or subtract a coin to match the baseline weight. Filling the hopper up about halfway seemed to eliminate the jamming problem.
