Amazon Customer•January 13, 2017
The box arrrived in good condition. The vanes of the radiometer are badly out of balance radially. One vane is out of position by about 10 degrees.
As such, for the money, it is not suitable for educational display of the Crookes radiometer principle. I am disappointed in the selection of the rotor that this manufacturer chose to put into the glass bulb.

Beautiful but poor quality control
Billy Brackenridge•August 25, 2016
Terrible quality control. The vanes are not evenly spaced, and when it does work it wobbles. I have another radiometer, and it works, but this one won't spin unless there is very bright sunlight.
The good news is that this is a beautiful product. It just doesn't work. I wanted to put on my table next to wine glasses. The bad news is the sunlight would need to be so bright that it would be uncomfortable to drink wine.
I have a radiometer that works, but it isn't beautiful. If you want a beautiful radiometer and don't care whether it works, this is the product for you.
If you get one that was built correctly, this would be a 5 star product.

Do Not Buy
Chris Walker•May 11, 2016
The first one I received had bent and out of balance vanes. I requested a replacement. I received the second unit and it was bent and out of balance just as bad as the first unit It was clear that these were manufactured this way. Very poorly made.
A MUST BUY !!
