## Customer Reviews

### ⭐⭐⭐⭐⭐ These are awesome stir bars - just make sure you actually have a decent stirring plate!
*by B***N on June 24, 2020*

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.

### ⭐⭐⭐⭐⭐ Great product
*by T***I on November 18, 2019*

The large size magnetic stir bar certainly has a much stronger vortex and thus the stir power more than other products. Great stuff for a great price.Works better than the other pill shapes I have used.

### ⭐⭐⭐⭐⭐ Came as one would expect🤷‍♂️
*by M***X on April 26, 2022*

Very fast. And only 2 inches in length(sorry I’m boutta go do something. Not gonna think longer). These things spin center for me. Maybe I got lucky. Ionkno. Thanks gangsta🙂
