### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great
  

*by M***K on Reviewed in the United States on January 10, 2018*

Have been using these for several years. I store tools in a wooden tool chest in a damp basement, no rust problems. Seem to last about 1 1/2 years, your mileage may vary.  Highly recommend

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    So far so good. No rust on any items after two months
  

*by B***S on Reviewed in the United States on October 27, 2014*

So far so good.  No rust on any items after two months.  I had the larger hanging Bull Frog rust blocker in the closet but it was too bulky and in the way when trying to put metal objects in and take them out of the closet.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Eliminates rust
  

*by T***N on Reviewed in the United States on August 24, 2020*

I’ve been using this product for several years in my large tool cabinet to keep rust off my tools and it does a good job. It has to be replaced every year to continue protection.
