Thanks to charlie i started my 48Q Igloo coolador about 6months ago,and cant believe how good it keeps the huminidy I am always at 69-70%,and my wooden huminidors run between 63-72%,the point is they are crap and out of 10 i already gave 5 away and will only keep 1or2 of them, thats how much i like my Igloo, and yes you can easy store 500 smokes in there, and get your solution for 7.50 a quart at the pharmacie! Amen
