Review on Younion Digital Automatic Counting Counter by Gerardo Goodson

Bought for my almost 4 year old to start teaching responsibility. He likes the idea of keeping money in the bank, but doesn't count his money accurately. The "sensors" on the coin tray are set to count the coin based on the passage through the area but my 3 year old can't push the coin down, either it's slightly bent or needs to push harder and then counts the coin several times times. This will probably work well for an older child. It's hard for his age. We leave him as he likes the concept and it is not too expensive. We're just not going to use digital money counting with any accuracy.
