I actually purchased this cooler, the NewAir AW-281E, for cigars. In the climate where I live, temperature is a much bigger concern (and much harder to manage) than humidity in preventing the dreaded tobacco beetle from hatching and devouring your smokes from within. To that end, this thing works like a charm! It got down to 66°F in about 10 minutes in an indoor environment that I can barely get below 80°F between May and October. (Even if I had an air conditioner capable of it, I couldn't afford the bill.) And thanks to its use of thermoelectric technology as opposed to old-school coils-and-compression, it does this at a maximum operating load of approximately 100 watts. Most surprising is that the interior, within about 12 hours, also reached (and has since held) a steady level of 67-69% relative humidity, as is, with no modifications (i.e. no substitution of humidified Spanish cedar shelving or drawers for the steel bottle-racks.) All it took to do that was three crystal humidification jars, 1 large and 2 small. In half a day it was completely ready for use. (Here, though, your mileage may vary remember that I'm describing how it performs in the quasi-rainforest environment of New Orleans. You may need a little more patience and a few more humidification devices in, say, Las Vegas.)
Please note, however, that had I been purchasing a cooler for storing / aging red wine, I would have gone with a compressor-driven model. Again, that's dictated by the environment in which I live. At an ambient temperature near or above 80°F, the thermoelectric method begins to reach the limit of its ability to provide the necessary 55°F interior temperature for optimum long-term wine storage. But it has no problem at all attaining the desired 65-70°F range for storing and aging cigars under the same ambient conditions.
The sleek black / stainless / glass styling on the exterior doesn't hurt, either. It's simple and utilitarian in appearance, which is all I ever want from an appliance aesthetically.
