## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked as advertised.
*by G***R on February 13, 2020*

Worked for our application. Would be nice to have smaller quantity containers. Needed 6 but price forIndividual pieces more that the container I purchased.

### ⭐⭐⭐⭐⭐ Exactly what you are hoping for

Not sure if there are poor quality ones on the market, but these are definitely to par with ones you have used in the past

### ⭐⭐⭐⭐⭐ It fits correctly
*by C***N on February 25, 2020*
