High quality PTFE coated magnetic stirrer bars. These are as good as the ones used in many professional laboratories.

Great value

Not great

They're bars ... they stir. Nice selection of sizes,

Great but the small ones will get little use

Sizes ranging from small to tiny, beware.

Good price, good range of stirrers, excellent

work good

Product quality is good

Products are good, same as described. I like the sizes. Perfect for my need.

I loved the range in size. The tiny ones proved to be very useful when mixing solutions in small amber bottles. All of the magnetic stirring bars work well and fit our needs. I initially wanted at least one long bar, but am glad for the sizes that were included in the set as I can mix and match to fit my needs. I definitely recommend this product if you find that you're in need as it arrived rather quickly. Storage and clean up are a breeze! With more time, I can provide an update on the durability of the stirring bars as we haven't had them to use for an entire week.

Good
