Wireless Add-on Mini Dehumidifier, UooEA Gun Safe Dehumidifiers 2 Hours Fast Recharge,Safe Detachable Heating Base Design,Portable Dehumidifier for home ,RV, Closet, Car, Small Space（No Heating Base）

I keep one of these in my gun safe in the basement. One in each feed container for my livestock. In the springish time when the humidity is crazy high, we would get grain mites from tsc feed bags. These keep the containers enough that they quickly die when I add a bag. Love them, and that they actually re-charge

Easy and quick to dry out crystals and reuse

Product has worked well to this point!
