Hot Plate Magnetic Stirrer with Stirring Bar, Magnetic Hot Plate Stirrer 100-2000Rpm, Hot Plate Stirrer with 180W Heating Power, 520 Max Hot Plate

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.

I purchased this product a few months ago and the magnetic spinner quit working. I contacted customer service for this company and they are absolutely terrible and did not correct the issue. They had me jumping through many hoops sending videos and then waiting 48 hours to get a response and then after many days of going through these hoops they said we need to see a video of it plugged in and running which if it's not working you can't see it running. So I've had enough of this company it's not worth the $50 that I spent on it it did not last and it's like a toy. I highly do not recommend this product if you're going to use it more than 10 minutes a day because when it fails you're knocking to get satisfaction. Buyer beware, Nevin. J

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.

Way better than a slightly cheaper one (that didn't have heat) the stir bar doesn't fly off to the side at a moderate speed like it does with my other. The heat is also nice for dissolving a gelling agent.
