2 Heads Magnetic Stirrer Hot Plate Digital Heating Mixer Dual Controls 2*20w

The box itself was punctured and sounded like broken glass inside, but when I opened the box it was all intact. I am satisfied. Hopefully, it can withstand chemical spills if they occur.

Won't stir large amounts of stuff. Can't be too heavy in there so keep that in mind.

Very good product , does what it says .. could someone please tell me what is the max time I can leave the unit on medium speed and warm hot plate . Thanks

I bought this for my daughter to use in her natural beauty products business. She’s absolutely in love with the ease of use, and quality of this product. It heats quickly, and the magnetic stirrer is fantastic!

Product review:I just received my 180W heater/stirrer unit today (2/14/19) and have been performing initial inspections and testing. I will report my findings with the understanding that the product has probably been through some manufacturing variations over time and may differ from other observed results.I found the product to be well-packaged and in excellent condition upon arrival. The thermometer holder 90-degree bracket had an internal burr that prevented its use without first filing it down. Otherwise the workmanship was visually quite good.A concern that I had, based on earlier reviews, was a lack of repeatability and/or smoothness of variation in the power settings for the two controls. I will comment on that in my test results below.Test results:The system was tested using a 200 ml beaker containing about 150 ml of tap water along with the included magnetic stirrer (volume unknown). A clamp-on ammeter was used to measure the rms current to the unit and a nominal value of 120 vac (not measured) was assumed for power calculations. When either of the two control knobs is “turned on” there is a significant rotation (perhaps 45 deg) to the “click” or first actual “on” position and an additional rotation of perhaps 210 degrees or so to reach the maximum point.The stirrer was tested initially and found to perform smoothly from initial startup position through maximum speed, though I would be unlikely to use it at anything more than about 40% of maximum speed. The current measurement for the stirrer was basically negligible at no more than 0.02 A rms (noise level of the ammeter used was about 0.1 A rms).The heating unit was tested to assess its power setting repeatability. The first thing observed is that the heating unit did not turn on (i.e. draw any current) until the knob was rotated significantly, at which point the current was 0.7 A or approximately 85 W. However, the knob could be rotated counterclockwise from there down to about 0.2 A (~25 W) before it dro

Works great

Wonderful heater/mixerGreat for the small jobs

Works great

Great product

This works perfect for my needs, I purchased one prior to this but had to return it because it didn’t have an adjustable heat setting. I am very happy.
