This is a great product at a decent price.
Large, powerfull magnets align with the stirrer's magnet and stays in sync (makes even low-priced stirrers perform well). The eight flat sides (octagional) enhance turbulance for a more effecient (and quicker) stir even as the viscosity is increased. This is a great product at a decent price. The coating appears to be real PTFE (Teflon) so they should be chemically non-reactive, and immune to heat.

These are awesome stir bars - just make sure you actually have a decent stirring plate!
I won't go and dis any of the models of popular stirring plates out there. I bought one, then ended up buying a set of ten 1" stirring bars to compensate for the inadequacies of the stirring plate I purchased, while at the same time buying another stirring plate for twenty bucks more than the first, and found that the new plate I bought totally rocked while the first one was mediocre.As far as the magnetic stir bars are concerned? Well the new plate works well with any of the stirring bars I have, and now I can use any of my magnetic bars without issue, but these won't perform like you want them to if you get a crummy stirring plate.I really like these, however, and when I want more "bite" in the solution to be stirred, I use these instead of my smaller 1" bars. These are affordable too, which is important. I highly recommend these.

Works great!

Unbalanced, possibly fraudulent.
None of them work correctly. They bounce around the glass and don’t rotate or stir the liquid like they should. Magnets seem very weak; seems like a fraudulent product.

Not good with my Stirrer
It only works on low setting with my stirrer, but may work better with a more expensive 1, I spent $80 on mine.
