It will provide lifetime protection for cases containing guns, cameras, telescopes, laptop computers, musical instruments and safety deposit boxes. Also, ideal for tool, tackle and jewelry boxes as well as a silver flatware box in addition to any small storage area that needs protection from the dangers of high humidity which could possibly cause moisture damage.

Review: Three Stars - These are a nice quality, however, the need "recharging" a LOT...even in a sealed environment with little moisture.
Review: Be Careful - This product does work well as a dehumidifier, but keep in mind that these are the Blue silica gel canisters which contain Cobalt. Cobalt can letch out some sort of poison which is harmful to some collectables like coins, comics and stamps etc. Some studies say in can also cause cancer if you handle cobalt often. I'm not sure you can get cancer from one of these, but why take the chance. Get the NO Cobalt version instead. The No Cobalt version is pretty much the same product but it is orange and not blue, and doesn't contain the poison. I switched out all of these for the No Cobalt version.

### ⭐⭐⭐ Three Stars
*by G***N on July 11, 2016*

These are a nice quality, however, the need "recharging" a LOT...even in a sealed environment with little moisture.

### ⭐⭐ Be Careful
*by P***0 on June 23, 2014*

This product does work well as a dehumidifier, but keep in mind that these are the Blue silica gel canisters which contain Cobalt. Cobalt can letch out some sort of poison which is harmful to some collectables like coins, comics and stamps etc. Some studies say in can also cause cancer if you handle cobalt often.

### ⭐⭐⭐⭐⭐ Works as expected
*by G***K on August 29, 2012*

Works as expected to keep my guns/ammo dry. All for a great price. I like the cobalt blue as it is easy to see the color change. Am not concerned about the carcinogens as the crystals are packed into the metal holder and cannot be touched directly.
