Just a little update - been sitting full now for 2 weeks and holding 65 percent like a champ. With the weather here, temp ranges from 68-72 but once it gets and stays warm and we turn the AC on it'll be 69 in the house so should hold around 68-69.
2 weeks running and only used 1/4 of a canister of water in each. I've got roughly 150 loose sticks in the drawer and 6 boxes on the shelves.
Worth every penny IMO.
