Review on Younion Digital Automatic Counting Counter by Michael Lara

Bought for my son who is 4 (almost 5). He is learning to count money and making money around the house and he loves it. The idea of this "piggy bank" is great, but the accuracy is not. We constantly have to count money. He counts ten cents on a penny and sometimes no money at all. Luckily it's young and learning, so we'll just open it up, reset the register and count manually. I feel the sensor needs a good upgrade. But overall a good start.
