### ⭐ 







  
  
    garbage. unbalanced. will not function
  

*by M***O on Reviewed in the United States on September 18, 2020*

i bought two packs of 4 50 mm bars. only two out of 10 are capable of spinning on a stir plate. the remaining eight are so off balance that they slam into the container wall after just one or two spins. at super low rotation speed, you can see them spinning off center by 1/3 of the length for a moment, and then they fly off.complete garbage. i didn't think to check them before preparing my cultures, and now the work and cultures are wasted

### ⭐⭐⭐⭐⭐ 







  
  
    Good product
  

*by M***N on Reviewed in the United States on May 18, 2020*

The stir bars are very handy for stirring up alcohol and shellac flakes. The different sizes allow me flexibility in choosing the container size and give me a well mixed product. Very pleased

### ⭐⭐⭐⭐⭐ 







  
  
    Nice stir bars
  

*by J***E on Reviewed in the United States on April 28, 2021*

Nice stir bars if you use 2 hotplate stirrers get 2 sets worth every dime
