Our 7 year old absolutely loves this clock! She is learning about energy provided by inanimate objects like potatoes. She has tried lemons and liquids with good results. Appropriate for a lesson that does not yell SCHOOL! Would be helpful for any child needing to learn to tell time.

This was exactly what we needed. Actually we only needed the clock, but it was nice to have the whole kit. Directions from the internet made it clear that you needed a particular, low voltage / current clock and there is NOWHERE to find one. My husband is an electrical engineer and he spent days looking for one with no luck (other than trying to build one, but time did not permit that).

Directions were the same as the internet, connected the clock and it worked. Our son brought it in for his 2nd grade science project and was able to explain in "2nd grade terms" what was happening. I highly recommend this product.

I needed a 1.5v clock for my son's science experiment. So I bought this product solely for the clock. It worked perfectly. The only knock on the item is the gauge of the wires from the clock to the power source are way too thin. Not sure the gauge, but they were significantly smaller that the smallest 20 gauge wire sold by the hardware store. We tested the 1.5v clock with a .8v battery, 1.4v battery and a 1.8v battery. The clock worked in every case! Great price and great fun!

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.

Of course my grandaughter had no clue about "potato clocks". But she was suitably amazed and it was a wonderful trip down memory lane for me!

The twisted wire connections felt fragile till I actually looked at the instructions and found out about the little pieces of tape that came with.

We wondered what we could accomplish if we put a hundred potatoes in series! ; - )

Bottom line: a perfect, elegant little gift for a grandad to give.

This is an item I would strongly advise anyone to purchase. It's all good. It is really easy to put together, doesn't fall apart and the clock really works. The price was excellent and it has been working quite accurately for several weeks. Actually, I plan to order two more for upcoming birthday presents.

Love this "toy". Sure, it's educational and all that but it's so much more. It's so easy for a child to put together although a young child might need a little help. It easy to do, doesn't fall apart like so many toys do and the clock actually works! Plan to buy a couple more for upcoming birthday presents. Can't beat the price either.

My daughter was thrilled to get this in the mail, but we were quickly disappointed in the quality of the item. Wires were too thin to stay in place and clock was unbelievably cheap. This product was not worth the money paid even if it did work. Our clock's buttons stopped working on the very first day. Everytime we moved or touched the potatoes, the wires disconnected and restarted the time, which was frustrating for my 9 year old. I would NOT recommend this item to anyone at any price as it is not worth it. It has such great educational potential, but fell short on every account. HOWEVER, I highly recommend AMAZON. They took this item back without hesitaion with no questions asked. They gave a full refund and even sent a label for free return shipping. Their customer service is top notch!!

I bought this potato clock for my daughter's science fair experiment. It is easy enough to put together, but setting the clock is a nightmare. Just when you think it is set, it flashes back to 12:00 even though none of the wires are crossing. We finally got it running and now, after a day, the time is wrong. I can't tell if the battery is draining or the clock just doesn't work. The experiment was to see which fruit or vegetable made the clock run best but we can't tell because the clock never seems to work. I have to buy one from another company now. But if you just want to see that the clock turns on, then this could be interesting.

My son, who is 9, wanted to do this experiment for his school science fair project. I bought this kit because I didn't want to have to run all over town trying to find each and every component needed for this experiment. I thought this kit was perfect because it came with everything we would need. This is a very cool project and my son got a real kick out of hooking it up. The problem is the clock is so cheaply made that when it came to set the time on the clock both of the buttons pushed in and became stuck so we could not set the correct time. This was very disappointing to us both! Unfortunately, he had to use this clock for the science project because there wasn't enough time to return it for another. Very disappointing!
