I'm looking at some of the suggested sites to order heartfelt beads....would you suggest getting the aluminum humidifier w/ beads, the tube filled w/ beads, or just the plain beads?..which would be easiest and most foolproof? If I get the regular ones..do I get the half pd? or full pd? The humidor will prob. be a 50 cnt. AND how long do the beads last? I'm sure all this info is already on past posts, so I apoligize for not looking... but I'm juggling 2 babies here and don't have much time to search...thank you so much for the help!:smiley9:
