I purchased this unit a couple of months ago. My initial use is for a large finished basement. We do not have leakage, but it helps keep from smelling musty. Quiet!!!

This little dehumidifier, about the size of a boot-sized shoe box on end, performs well. Although essentially all plastic, it is still sturdy. It is ideal for small spaces; I have a 6'x'10x8'h brick structure that is up against a hillside, so quite a bit of moisture comes through two walls even though they are moisture blocked. This unit extracts about 1/2 cup of water per day when the space is closed. This is just enough to satisfy my needs and prevent deterioration of contents. It wouldn't draw enough for a larger area. It would be very good for walk-in closets, even larger than my space, since they would generally have less moisture than I have. I don't believe there would be sufficient benefit for use in a living area since the unit would be overwhelmed by ventilation, having such a little volume capability. This would also be ideal for enclosed spaces in coastal areas.

It works spectacularly well if used for an enclosed space where the air isn't being circulated/exchanged. I have it in a guest-cabin behind my house which sits vacant 90% of the time. It extracted about 1 cup of water in 24 hours of summer weather. Over a period of a week or so, I expect it will remove most humidity as long as the cabin stays sealed. There are 2 keys to this unit working effectively: (1) It works slowly, so expecting it to dehumidify your bathroom right after your shower is preposterous. (2) It's not going to work if the air you're trying to dehumidify is being circulated. In other words, if it's a room you're constantly going in and out of, or a room connected to your central A/C unit, forget it. You'll need a big, mechanical dehumidifier. But for spaces where the air isn't being circulated/exchanged, it will eventually extract most of the moisture and keep it dry. A perfect example would be a motor-home. My only (minor) complaints are that optional drain hose is only about 4' long (so I replaced it with a 1/2" x 6' hose from HomeDepot for 3 bucks.) And the power converter gets very hot, so I hooked it to a lamp timer and have it running 2-hours-on then 1-hour-off all day (thus a total of 16 hours a day). Hopefully this will keep it from getting seriously hot. Bottom line--perfect for enclosed spaces but wouldn't recommend for areas where air is being circulated or exchanged.
