Works great - Hydrosorbent 900 Gram Silica Gel for 66 Cubic Feet SG-900

I use this product in my 35 cubic foot gun safe to keep the humidity down below 52%. I have three of these and a dehumidifying rod and I have no problems keeping the humidity in the safe at an acceptable level. Humidity control is very important especially here in Florida. I only have to recharge the product every 90-120 days. I would highly recommend this product.
