LAB FISH Lab Magnetic Stirrer 1800Prm, Magnetic Mixer, Maximum Stirring, 3000Ml Capacity Stirring Plate with Stirring Bar, Egg for Lab and Home Fermentation

The machine works as intended, but I bought it for magnetizing nail polish, and for that it's just meh. In order to get a good glass bead you have to hold your nail towards the magnets or it will be very diffuse. Completely defeats the purpose of being able to rest my nail easily on a magnet for two minutes. Again, not what this stirrer is intended for, so I'll give it 5 stars for being quiet and easy to adjust the speed of the spin. If you want something for magnetic polish I'd suggest finding a device with bearings to keep the spin going and right over your nail, not underneath. There's a few 3d printed ones out there, I'm going to try one and hopefully it goes better than this. I have seen where people put the 3d printed magnet with bearings on top of this machine, and it spins the device with no input from the user. Maybe I'll try that and this purchase won't be a total loss.

I use these in 500 ml masons with mycology medium, and the stirrer works perfectly for those. It seems strong enough to do larger containers as well, but I did not test larger containers. The single stir bar included is weaker than the ones I purchased separately, but even it does the job on the masons I tried. The stirrer works perfectly with smaller jars, likely to at least a liter, maybe two depending on how vigorous a stir is needed. It is perfect for my small mycology medium jars.

So far works great. Decent quality.

Works exactly as described
