Works as expected.
Yep…good to have several of these. Some get lost and some get accidentally dropped into the fermentation chamber with the wort. The middle raised area, used for reducing surface contact to give better reliable stir, works great. 16hrs on the stir plate, yeast starter was ready to go. Fermentation was noticeably apparent within 4hrs of pitching the yeast. Highly recommend for your starter yeast.

Works well
Works well with my magnetic stirrer. Great for agitating shimmer ink in slim bottles like Ferris Wheel Press

Proper stir bars
Spin and mix as intended, reasonably priced, I’d buy them again.

Trash, not suitable for any lab usage at all
If you are looking for accurate temperature measurement, DO NOT BUY THIS TRASH. When measuring boiling water, it shows an offset of approximately 4 °C from the expected value.

These work
I use these for stirring liquid mycelium and herbal extracts in ethanol. They are heat resistant in a pressure cooker at 15 PSI. No problems after a few uses.

Worked perfectly for smaller vessels
Perfect for liquid culture in pint size wide mouth jars. Small and well balanced, they spin freely and evenly. Handled 30 mins in the autoclave without issue.
