These are awesome! Plenty of sizes to make sure that your stirrer isn't
stirring too violently. I use one in my magnetic coffee stirrer that I made
out of a USB computer fan, a harddrive magnet and one of these. Having
different sizes makes it easy to find the perfect medium for each mug.

Really good deal compared to the other options. I only needed 2 of these but it was cheaper to get this set of 7...even though I will never use the smallest two, I couldn't see them functioning to stir anything much bigger than a thimble. For homebrew starters the middle two sizes are about perfect. About 2.5 week shipping time, I am still waiting for the one I ordered a week earlier than these on ebay actually.

Quite strong little magnets for a stirrer. I use them for making colloidal silver solution. They work well. In a convex-bottom jar they tinkle due to the rib in the center. Tick, tock, tick, tock. That way you don't forget they're in operation. Good stuff. Get 'em.

Having the different sizes, and for this price, allows me to spin gallon jugs easily as a small vile. If my daughter had not thrown my first one down the garbage disposal, I would not have had these with the center spinning ridge, which lift the outer edges off the surface as they spin, reducint noise and facilitating the spinning better. This is the best of these devices, especially for the price.

I'm all in favor of American made, but magnetic stir bars from domestic suppliers are greatly overpriced -- and not necessarily made in the US anyway. These are a great bargain if you don't mind waiting a week or two. High quality at a low price.

very small to pretty big .. they all worked in my homemade spinner, the smallest worked mixin a raw egg at 3600 rpm ... this means they are balanced pretty good, however i didn't do any video to see if they are actually spinning on axis or slightly off, but they worked great at full speed, spinning in the flask with no liquid all worked at top speed of 3600rpm

This product meets and exceeds my expectations. High quality of the bars and the variates of sizes for the price is great.
And the package arrived WAY BEFORE the estimated date. Very happy a great buy :-)
