Purchased for my brother-in-law who recently launched to the cigar kingdom and decided to be a permanent resident there, LOL 
He monitored it for 3 days first to make sure it would maintain a stable temperature and humidity that would not harm the cigars. Then he found there were no big temperature changes. Now he has happily placed 320 pieces of his collections to this slick cigar humidor and thanked me over and over again :)
