Afloia Mini Dehumidifier

When I first received this I had high hopes. All looked to be well constructed and of good quality materials. The drying cartridges seemed large enough for my use. I am using this in a safe, with a door that shuts tightly against a gasket. I am not in a high humidity location, I am in New England. We have had a very wet winter, but that has not raised the humidity for extended periods. I can't say this item doesn't do what it claims, but I find this item to be far overpriced based on its performance and would not recommend it. My problem is with the ability of the cartridges to absorb moisture. I am not sure what type of silica beads the manufacturer used, but they seem to have almost no capacity to absorb moisture. I do not open this safe frequently but the beads in these cartridges turn black in just 2 -3 DAYS in the closed and sealed safe. I have used other devices with silica beads before. These would give me 2 to 4 WEEKS before they needed recharging. If I have to tend these cartridges almost daily they are more of a burden than a benefit.
