Review: Great product! - I bought this product to teach my children in a fun way about digital time. We all had a fantastic time discovering the various fruits that can work the clock. Also, as the fruits have wilted, the children have been amazed by the drying up process and discolouration of the fruits. My only worry, and it is a big one, is that the instructions with the potato clock state that the electrodes can be placed in various liquids to make the clock work. I was a tad concerned that this would give my children the false impression that they could put any electrical worries in water to make a product work. Therefore, I removed the instructions and never mentioned anything about using fluids to power the product. All in all this is a fun product that gave lots of fun, investigation and learning. I am delighted I bought it!
Review: Works okay and good to demonstrate - Could be slightly better quality as the gears could engage better. Clear plastic enables me to demonstrate and it works by a good old puff in the class room so had fitted my STEM brief well.

### ⭐⭐⭐⭐⭐ Great product!
*by L***Y on 12 September 2009*

Also, as the fruits have wilted, the children have been amazed by the drying up process and discolouration of the fruits. My only worry, and it is a big one, is that the instructions with the potato clock state that the electrodes can be placed in various liquids to make the clock work.

### ⭐⭐⭐⭐ Works okay and good to demonstrate
*by J***S on 23 April 2023*

Could be slightly better quality as the gears could engage better. Clear plastic enables me to demonstrate and it works by a good old puff in the class room so had fitted my STEM brief well.

### ⭐⭐⭐⭐⭐ Easy to assemble, works perfectly
*by J***I on 11 September 2022*

Used this to demonstrate wind power for Cubs/Scouts. It worked perfectly as shipped, but I actually soldered the electrical connections and assembled the generator block to keep it simple for the younger ones.
