Durable and Long-Lasting!
I've only had to purchase this item once because of how reliable the product is. I can't say they're the best stir bar money can buy, but for the price it's definitely worth it. These stir bars have yet to lose their magnetism! My biggest problem with stir bars was always how long they stayed magnetic, these were the solution. HIGHLY recommended!

Very quality, just a bit small for my needs
These are a bit small for 1.5 pint wide mouth jars, they will work but you need to use high speed. does not work with more than one with my equipment, not sure the magnet strength is high enough to work in groups of 2 or 3

Wobbly and unbalanced
Horrible balance, only 2 of them are able to spin at a high enough speed for airation

You get what you pay for
They don't spin well but they are cheap and you get a lot of them. Depends on how important consistent spinning is for your applications. Sometimes these cheap ones are fine for me but for important chemical reactions I go with my $25 single stir bars...A good product overall when considering its cost
