This humidor is not good for your cigars. It is not a thermo-electric. It is a compressor refrigeration system and literally sucks all humidity out of the humidor. I would advise anyone to refrain from buying this since it will literally ruin your cigars. The only way it actually maintains its humidity, is if you un-plug it and use it as a regular humidor. I tried processing a return but since I passed the 30 days warranty time, they won't process the return. Which is ridiculous since I honestly wanted to keep this and have it work properly like it was marketed. However, I now know, the fundamental issue with the humidor is the compressor refrigeration system.
