Overall best product I've bought to keep my cigars staying fresh. I takes sometime to get it exactly at your desired humidity level but after that it's perfect. I would recommend that for anyone who decides to get this product to take there time and read through the manual first. But just in case when you season this whynter humidor your supposed to while the unit is off and you must let it sit for at least a day or two before plugging this unit in. I've own this product for almost a year and no major complaints. Don't sit it by a window or next to any heating system it will start to throw off your humidity levels and I suggest to check it at least once a week to make sure whatever humidity crystals or beads your using in the humidor did not dry out.
