I just received the Spanish cedar trays from Amazon, and I am quite pleased with them. They are a little short for the igloo cooler (25 qrt.) but I think I am going to be very happy with them the RH dropped to 60 right after I put them in but in less than 24 hours RH is now 64% and climbing. once it settles down I will transfer cigars to trays out of boxes. I plan to place some strips for the trays to rest on above the KL crystals. I also am thinking about getting two more, but I probably just keep the three boxes that I am using now.
