Make sure you pay attention to what coins you are putting in this jar as well as what the jar is registering the coin as.. Mine counts all dimes as a penny....

Makes money hard to put in, and does not calculate correctly

It was a little tough to push the coins in and using the plus or minus buttons was a little tedious because the plus sign only adds 1 cent when you push it so if you have a 1$ coin you have to push it 100 times. It was also just too small for me once all my coins were in it was practically full

Counting is inaccurate. Often mistakes pennies for dimes.
