the cups are not able to hold anything larger than a very small potato

Finicky at Best

These potato clocks are very finicky. It is not hard to make the connections so they will turn on, but it is nigh impossible to get the connection strong enough to actually use as a clock. The weak connection will again and again cause the time to reset to !2:00. I don't recommend this item.
