United Scientific RADIO1 Radiometer

Radiant energy should get 5 stars not the product. lol

Works like a charm. Will absolutly do the job for the price. Nobody needs a top of the line Radiometer lol. Runs pretty damn fast on a sunny day.

The quality is disappointing to me. The vanes appear to not spin as easily as the higher quality radiometers, so the performance is comprised. Other than that, it looks nice. I've owned several over my lifetime but this one just doesn't make the grade in my opinion.

Son loves it and came quickly...

The radiometer doesnt work. Ive placed it in multiple well lit environments and the blades dont spin.

The product was old. The panes bent and had heat burn holes. The item did not turn with a flashlight.

Didn't work, even in bright sunlight. The metal pole appears to be bent so I think the spinner is contacting it. Even a little bit of friction will prevent motion.We already have another radiometer and that one cost less yet works fine.

2 units, first one the inside parts were broken on arrival, the second just didn’t work. Waste of money

Internals a bit inconsistent. They are fragile. I bought two. One was okay other wobbles due to poor quality control. They both work.

Works fantastically in Sunlight - that is what this powers this item - if yours does not work try putting it in the SUN

There is no real quality; and would not even turn/spin in the daytime sunlight, so I do not know what to say. I did return it.

It arrived with a crack in the glass and base was scratched. It did not look new at all. Returned it. A waste of my time.

Works, but only just. Pay a bit more for a better one.
