I hand mist 3x/day with a motomister, (saves on the hand, let the batteries do the work). Also use a zoomed dripper, that drips into a large plant. I supplement with a cool air humidifier next to the cage.. Only big downfall I see is if you want to go away for a day or so, an auto system would really be best. This has worked for me for 6 months, though.
I only hand mist my dart frogs. I let the mist king do the misting for me. I used to hand spray, but the amount of water my mellers wanted was causing my arms to hurt. It just wasnt feasable anymore. But I still have a large hand pump sprayer in case the power goes out for a while and the mist king cant run.
I hand mist, I have a habba mister, and I have a homemade dripper. It's really dry here right now... I have to try pretty hard to keep the humidity up. I really want to get one of those motomister things though cos it gets so tiring using the one I have. It was meant for misting bonsai trees, so yeah not that great for this.
I'm hand misting. Only one chameleon, but I find it a horrid experience and I am getting a mistking. Or rather, a family member with some $$$ is getting me one because he saw me standing there misting a cage that's 7 feet in the air and felt bad haha. When she was lower it wasn't awful now that I put her cage up and she's now a real tree dweller my arms feel like they're going to fall off. Priscilla gets mad when I stand on a step ladder.
i have a MistKing running into 2 of my large chameleon cages. i mist an extra 5 cages by hand. or use my reptifogger when i just want to relax and watch my guys but too lazy to mist by hand.. which happens alot at night
[EDIT], i will be running a mistking to 3 or 4 of my other cages, seeing as those species require roughly same humidity.. ahh life will be a box of jello after that
