Review on 🧪 INTLLAB Magnetic Stirrer Set with 7PCS Stir Bar Collection and Convenient Stir Bar Retriever by Shawn Sanders

The DC motor mount bearings started making noise and after a few months we were having trouble spinning at low speed in our almost continuous use case. It has a hard time stirring anything thicker or heavier than fresh extra virgin olive oil, but after a week or so the oil thins considerably. There was no heating at the device and very little excess unwanted heat entered the sample (tested with a newer thermal imager). A few weeks after the bearing noise started, the engine had trouble starting, but then eventually stalled. Transformation.
