They seem to work great and are easy to use. Way better than filling up a humidifier with water!

Your general opinion of this product.
These are very easy to use and stay good and freshness locked in until you open the bag and are ready to use them. Much easier than having to add water or gel to humidifiers without being able to control the humidity. These packs activate when necessary and absorb when there is too much humidity in the case or instrument.
