VONOYA Magnetic Stirrer, Magnet Stirrer with Digital Temperature Display & Speed Adjusting, Magnetic Mixer with Hot Plate & Magnetic Stirrer Bar, Home Lab Homebrew Kitchen Stirrer, 200W, 1000ML.

Bought to stir 3d printing resin in the bottle for less air inclusion. Want sure about whether it could stop thick liquid in bottle with a slight dome bottom, but it DOES! Can spin a longer stir bar easily - the heater is frosting! Have to be careful and not set the heater too high ( can heat to 300 °f) that bottles melt- watch closely on digital readout- heats a 1 L bottle from 70 to 85F while stirring in about 7-8 min 🤗. I don't have to keep my whole room at printer temp now! The integrated test stand holds the thermo probe conveniently while stirring.All the things my computer-fan-version hoped to be and it was much less than $100 and pretty well made and engineered

I recommend this stirrer for small / medium projects. I have no issues with it, it heats up fast and is very accurate. Worth every penny.

First let me preface this with the fact that I am a chemist with 20+ years experience. I wanted a cheap hotplate/stirrer to melt some solid low m.p. fats. It works for that purpose but it is far from lab quality. The manual was clearly written by a non-native English speaker and contains hard to read, contradictory information ("C setting, which shows default value of 10.0, please do not adjust it" and later "Temperature slow to respond - C value is too big, adjust it"???), inadequate or nonsensical information ("separated into low and high pressure system"????). The Sc parameter is supposed to correct the displayed temp to actual value but does not (4-10 degree discrepancy as measured by an independent temperature monitor). Most of the adjustments are inadequately described or not described at all. The stirrer cannot be operated independently of the heater and it won't heat at all without stirring. Could not get it to heat at all beyond 180F. All temps are in F not Celsius and no way to switch to C. PID control is questionable - as another reviewer noted it seems to be full on or not at all even when close to setpoint. But it does melt my fats and stir them. Just make sure before you buy that with these issues it is adequate for your intended usage.

As with almost all inexpensive plates, this one can't heat 500ml much past 150F, but you get what you pay for. This is a solid unit for warming and stirring. Temp display is limited to F.Based on my experience, this unit competes well with anything below $250. Its a decent bargain at its price point

I was surprised that my 2 liter Erlenmeyer flask was too tall for the for the probe stand. Even the 1 liter was too tall. Guess you can only use beakers. My 2" stir bars flew off the magnet. Only the .5" stir bar that came with it would stay put. Being a homebrewer, I use the stir plate for yeast starters, usually 2 liters or more, so I'm not sure this is the one you want for that use. BTW, the probe doesn't set securely in the probe holder. It just dangles there. Later 4/15/22 heater stopped working. temp LED say 190 all the time. I'd like to return this. It is obviously non-functional. Now 4/15/2022 heater stopped working. Hope to get a response form the company.Now a month after my last review 5/14/2022 and still no response. I guess that says a lot about the company's backing up their product.

The magnetic stirring component of this unit works very well. My praise ends there. The digital readout is nice, too bad the unit doesnt hold that temp... I'm not sure if the thermocouple failed or what but had it set to 70f and after less than an hour on the stir plate, I couldn't handle my beaker with bare hands it was so hot. Destroyed the sample I was working on in the process. Very disappointing.

Perfect for infusing edibles

I've been using this stirrer for a while now. All steel construction, and the temperature controller has more features and intelligence than I'll ever use. Couldn't be more pleased.
