This item effectively removes moisture from my gun safe and requires no electricity or anything from me to work. Once the unit is saturated with water you simply bake it in the oven for a few hours on 250°F and then let it cool off. Then put it back into your safe and it will absorbe more moisture and is rechargeable by baking the moisture out of the can over and over again. It lasts forever. It lasts about a month and then needs to be baked to recharge it. At least in my area where we have high humidity.

These large metal canisters are awesome. I think the metal canisters will outlast the cloth bags, but time will tell. These large silica gel containers work out much better in a larger storage container.
