The stirrer comes with a one-year limited warranty. This magnetic stirrer is used by researchers, professionals, and hobbyists to stir a variety of liquids and solutions in chemistry, food and beverage, pulp and paper, lab, and home applications.
Researchers, professionals and hobbyists use a magnetic mini stirrer to stir a variety of liquids and solutions in chemistry, food and beverage, pulp and paper, lab, and home applications. Magnetic stirrers have a rotating magnetic field that causes a stir bar, immersed in liquid, to spin and stir the liquid. A magnetic stirrer is quieter, and more efficient than a motorized stirrer, and has no moving external parts that could break or wear out. Because of its small size, a stirring bar is more easily cleaned and sterilized than manual stirring devices, and does not require lubricants which can contaminate the reaction vessel and the product.
Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards.

That said, I should point out three limitations, but, at the price point, I think they are fair limitations.
First, the rheostat (speed) control is not a true power off switch. Yes, it controls stirrer speed, and there is a detent click "off," but listen carefully, and, while the stir bar stops, a motor continues to run when the switch is turned to "off." The power on light continues to glow as long as the stirrer is plugged in. Look in the manual, and the instructions say to pull the power plug if you won't use the stirrer for a while.
Second, there is no protection for the rheostat (speed knob) if liquid should spill. The illustration shows a standard Griffin (open) beaker. I prefer Erlenmeyer flasks for their narrow openings. Less evaporation as well.
Third, the rheostat / speed knob is recessed under the top lip, and, unless your fingers are tiny, it takes some attention to adjust the speed or to turn the unit on and off.
If you're willing to live with the inconveniences, especially of unplugging when not in use, the unit appears robust and should save you some money if all you do is stir up sugar water to feed yourself and the hummers. However, ...
If you're willing to spend approximately double the price, order the Scilogex 86143101 Model MS-H280-Pro (also from Amazon).Read more ›
If you are considering a stir plate for home brewing, this will do the trick at a reasonable price.
This only comes with one tiny little magnetic stirring pill.
It works. For how long? I don't know.
