Review on 🌬️ Solar Powered Glass Windmill Radiometer with 4 Blades - Light Mill for Study, Teaching, or Home Office Use by Joseph Rasmussen

I have owned several radiometers over the years. Some just stopped working (probably air leaks) or didn't spin well or broke. The latter had to be in direct sunlight before it started spinning. Luckily my cat knocked it over and it broke, forcing me to look for another one. This is the one I chose. It was reasonably priced and looked functional without being overly decorative. Well when it arrived I opened the box, put it on the open table (I was sitting outside on my patio) and it IMMEDIATELY started spinning. and it was in deep shade with no direct source of heat. Since then I've noticed that in the evening/night it slowly stops as expected but starts spinning again early the next day. In fact, I was drinking coffee on deck just this morning when the sky cleared and the radiometer began to rotate slowly at first. Without a doubt, this is the best radiometer I have ever owned. Anyone who has ever blown glass to make this radiometer deserves a gold star and a promotion. Could not be better!
