Magnetic Stirrer Hot Plate w/Stir Bar,100-2000rpm Magnetic Hotplate Stirrer, 180W Heating Power Hot Plate Stirrer, Max 520℉ Hot Plate with Magnetic Stirrer

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 have found the product to be excellent so far; it performs well and offers great value for its price.

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. . ."

Well constructed, clean, no BS, cheap, sturdy little unit. And the magnetic stir feature is well tuned and works well, which is something I was worried about. My only complaint is the heat, it's not very powerful at all. So much so that I doubt it's hitting the claimed wattage output.I've had 300-200mL of tap water in a 500mL Erlenmeyer flask on this for about the last hour or two with very light stirring and full heat and I'm only barely getting to boiling. It's certainly not a powerful, rolling, foaming, kind of boil though. Outlet can run a 1500w space heater without problems, so it's gotta be this things heat element.So, it's maybe good for extremely small volumes, low power organic synth, or getting organic solvents boiling. I could see this being AWESOME for reactions that need a constant, low heat for ages. But it's not great for anything more power demanding. You're certainly not going to dehydrate sulfuric acid or distill mercury with this.I may return, then again, I may try and remove some length of the heater wire to up power. I could also set it aside for the above mentioned reasons, since it would be the perfect tool for that purpose.

Love this hot plate/stirrer! It stirs and heats, which I use all the time for science demos in my classroom. And the price is well within my budget—much cheaper than what I could get in a science classroom supply catalog!

The Magnetic Stirrer and Hot Plate arrived on time. However, 1) the hot plate temperature could not be controlled by the potentiometer. It was more-or-less random, regardless of setting; 2) the hot plate has a crown on it (convex) of about 3 mm (1/8") which makes a flat bottomed beaker rock. Very annoying; 3) the magnetic stirrer control is much too sensitive, so I couldn't adjust it for smooth stirring. My older (broken) hot plate had none of these problems. Highly NOT recommended.

Been using for a few weeks, great product.

Works great!
