I purchased this unit for my daughter and out of the box it works great (provided you have two taters around).
This is the definition of plug and play. A wonderful way for kids and adults to marvel at the power of simply battery design.
The blue color made it a bit more fun than my black one i had as a kid. $15 winner in our household.

This was perfect for my son's science fair! It was very easy to work with and it came with easy instructions and other information that was very helpful. The potato clock along with some added poster boards and charts turned out to be a success as a science project. This product was fun and it did the job in showing another way that electricity can work as a source of power and/or energy.

Ordered this for sons science project as school, It worked great and he used it on several different type of fruits and veggies. Did not win any awards because teacher said it had been done so many times before.

I was surprised by how well built this clock was, the cathodes and anodes are all heavy gauge metal and durably wired. It has been over a month since I assembled this and the clock is still accurate to the second. In contrast I purchased several of the 4M potato clock kits as gifts and they would lose a couple minutes a week. I did not expect to use this as a "real" clock but you totally can. Then again, maybe I just used some really awesome potatoes.

Well I plugged in my potatoes and it worked, but not overnight. I don't think that the device is at fault.

Perhaps I used the wrong potato variety? At $.75 per these are expensive batteries.

I purchased this as a neat little science project for my nephew. I figured he would get a kick out of running a clock on potatoes. Well, when you get a kid to do something as stupid as plug a clock into a potato and nothing happens, you can imagine how the interest wanes.
Anyway, the return process was good, so I'll sport a star for that.
Epilogue - I purchased a flimsier version from Radio Shack that worked first try. It's a shame, as I liked the setup of this clock, and, if it had worked, it probably would last a good long time.
