We keep our house at 70 degrees, so the cooler holds about that temp, temp may change 1-2 degrees, right now cooler but is at 69 degrees and 63% RH, thermostat is at 70. Most members on here use Bovedas, But I use kitty litter primarily. The biggest advantage is it is completely trouble free, I have added distilled water once since I put it together a couple of years ago. I have about 300 cigars in mine. I have two cedar boxes and two cedar shelves, I switched to plastic baskets the last time i needed more containers from the dollar store. If you have any questions I'll be glad to answer. I have a 52 quart Coleman cooler.
