If you are to believe their website, the unit is reusable for ten years and would save hundreds over continuous use of damp rid....just plug in and it dries out. Even though the website says that it lasts 30-60 days and is sized for a 500 cubic foot space, in the relatively humid and cool environs of a 7.0-15 cubic foot area it may need recharging more often....even so, if it works, it sounds like a good deal at $25.
How long (and how much moisture) does Damp Rid last and cost?
I think I will try it and report back if no one else has bad experiences to share....who knows maybe two would work better?
