Great price , However a total piece of junk thats why they are so cheap. I have tried 2 of them and they do not mist, another issue if you contact them for warranty they will have to refuse since its not purcased from home depot orthem directly. If you have a need for the battery get the combo and you might get lucky and find one that works. I don’t know about the other model might be worth a try for 20 bucks if you have a battery.
