Have been using two of these in a 12 gun safe and they work fine. Recharge time is about 24hrs. 1 is supposed to be big enough, but I found I needed 2. Regardless, they work. Just bought a bigger safe and will be purchasing some more. Being able to plug them in so they can be reused over and over saves money and hassles of using throw away driers.

How Do You Know

Okay, bought one for about a 10 cu Ft safe. Arrived fine, wrapped in cellophane but not any of the pellets 'appeared' to be any color. BUT either hold it close to a light or use a small flashlight and then you can see the obvious color of the front pellets. I actually thought that the three color ovals would 'illuminate' (silly me) for the reading. So far no rust on anything and that is what it is supposed to do.

seems to work well. every 3-5 weeks it shows that it has absorbed a full amount of moisture. just plug it into the wall and let it sit over night and then pop it back into the safe. i have no rust or pitting of any kind so it must be doing something right

All you do it place the item in my safe and that's it! I check it once a month to see if the beads are pink, if so, I plug it in over night and they go right back to BLUE. Thank you stack-on for making such a great (easy ti use) item.

I have had this bought for me to put in my gun safe upon my return from Afghanistan. I am so pleased that I am buying another one for my other gun safe. Easy to use and no problems yet. Good job with this piece of equipment.

the best solution

Simple to use. Hang in safe, it absorbs moisture, pellets change colour/guage reads wet (depends on model), you plug it in the wall for 12 to 24 hours to dry the pellets back out. Couldn't be easier. Safer than a power cord unit: no fire hazzard/electrocution hazzard of frayed wires.
