Works great - Wheeler Engineering Golden Rod Dehumidifier

After a few years of keeping this thing plugged in my safe, I can honestly say that it works great.

When you open the safe, you can clearly tell that it's a few degrees warmer inside than the outside, and that's all you need to prevent condensation from forming on any metal or glass parts on the inside.

Obviously, the metal rod is hot to the touch, so that's not recommended. However, it isn't hot enough to damage the carpeting on the interior of the safe or any plastic/fabric parts that may come into contact with it.

So far, so good.
