Magnetic Stirrer Hot Plate - 716°F Temperature, 2000 RPM, 5x5 inch, 180W Heating Power - Magnetic Stir Plate Mixer with Digital Control for Scientific Research, Homebrewing, and More

Received and tested. All works as described. Heat pad did not make it to 500 degrees but did go 488 which is no big deal to me. With a non-viscous liquid such as water the spinner does not go slow enough to prevent cavitation. I can turn it down all the way and a fraction more it cuts off. But at the lowest point prior to cut off it spins fast enough to pull in an occasional micro bubble. I don't think this would happen once I added a foreign material but would be nice if it had a little mor control at low speed.

It arrived, packaged well. I tested it with a 500 ml beaker full of cold water, with the stirring on about halfway, and slowly increased the temperature over time. The heating and stirring work well. The attaching arm could be a bit better, but for the price and getting the job done, it's a great item.

Impossible to control heat. I needed a range of 60c-80c after fighting with it for 2 hours I gave up. As soon as it's on it goes from cold to 120c with no control at all. The stirrer goes from off to extreme speed with no way to slow it down. Worthless device should not be for sale. Awful. I will return.

It was a Christmas gift for my son. He was very pleased with it. Not sure how he plans to use it, he is an electrical engineer. I was impressed with how secure it was packaged to prevent breakage.

I bought this for my hobbies needs and was surprised how well it works. It gets quite hot and can make awesome hot chocolate for the grandkids. They enjoy doing science projects with grandpa. Next, I plan to take over the world! "Insert evil laughter here. . ."
