good solar cell - forget the motor Review by Clif
Price
Value
Quality

The solar cell provided is, as with any solar cell, very sensitive to light. The motor however is very insensitive to the voltage supplied by the cell. Even in good sunlight, you will likely have to give the motor help to get moving. Then, once moving, the speed is only grossly responsive to the voltage from the cell. Direct sunlight will keep it spinning nicely. Reduce the brightness by much and the motor will slow to a halt. The supplied paper patterns are of no real use because the motor speed cannot be carefully varied enough to produce interesting optical phenomena. The spiral pattern either spins to a blur or the motor stops.

I dumped the motor and hooked up the cell to my digital voltmeter. In this way I have a very sensitive light-meter for the $10 price of this item.

tight seal Review by Duane/Taylor

i like the product but the package comes sealed way to tight and there is no way to hold up the fan and once in a while you have to flick the blade to get it started but once you get it out of the package and find a way to set it up it works good.

Fantastic Teaching Tool! Review by Bob

This is a great tool for introducing the concept of solar power to kids. Sit back and watch their eyes open wider as they gaze at the sun's power. The only thing I would change is to make it more sturdy for handling without breaking.
