OK for the price...

This simple classic demonstrates the building of a battery using nearly electrolyte source (tomatoe, potatoe, lemon, orange, apple, etc). The clock is of very low quality with poor switches and half the indicator segments were non-functional out of the box. This was readily repaired, but is typical of these low cost kits. Regardless, my son (6) and I had a good hour or two of fun together playing with this and demonstrating the principals.
