I've read what I could in some of the past threads about these two systems, but I still had some questions. Has anyone had any bad experiences with either? Are the nozzles interchangable? I'll be using this to mist my rack of 12 tanks, probably with one nozzle per tank. The only benefit that I can see of the Mr. Moisture is that it's $99 and I can avoid shipping charges by purchasing it from a local herp shop.
