Mag-nificent
If you get a magnetic stirrer, be very careful placing the magnet back on the base for storage. If the poles are misaligned that little white pill will go flying. It took me 3 days to find it the first time it happened. The second time it happened I swear I was being careful, I looked for 2 days and decided it would be wise to have more the one stir bar and that's how I ended up here. Now, I'm not going to say these are the greatest stir bars of all time, but I still haven't found the one I lost, and I haven't lost one of these...yet

Works perfectly
I lost the original that came with the stirring cup. This fit the cup perfectly. Works just like new again.

Perfect size for mini magnetic stir for fish tank testing
These are slightly bigger than the one that came with my Auto Aqua smart stir I use for saltwater testing. great to have a few extras on hand as they are smaller than a TicTac and can be misplaced easily. I ordered the 10mm and very satisfied with their performance.

The larger size work better in 2L starters
I noticed that when I used my original stir bar that came with my stir plate, it struggled to spin in a larger 2L starter. Definitely help with achieving a nice vortex and providing the aeration the starter needs.
