This is truly a beautiful and delightful piece of furniture. The magnetic seals work wonderfully and there’s a tight fit on the drawer. Enough has been said by others about the need to seal the hole in the back of the cabinet.
As to the 1500 count, I would say that you would really have to do some work to get that number in, due to the lack of uniformity in box sizes, etc. If you use the shelving units, the reduced headspace for boxes and the need to allow space for circulation of humidification will significantly reduce that number. Still, I am using a single shelf and with just a little work could get in 1,000 pretty easily. While the shelf is nice for organization, I may ultimately remove it to improve circulation and increase capacity.
I do wish there were more dividers provided for the drawer, given its size. The drawer alone is easily capable of storing well over 100 cigars while still allowing more than ample circulation.
Overall, I’m very pleased with this beautiful cabinet humidor.
