You'd think they would work. I mean, they're just mist sprayers, right? [SEP] I ordered these to mist my germinating sunflower seeds to keep the soil moist. Keep in mind, they come in a pack of three, and I've only used one so far. Maybe that's why they come in a pack of three, because the one I'm using now gets stuck. What I mean is, the sprayer head that you press down on to get the mist to come out gets stuck. It sticks down when I press it. It worked fine for the first 25 or so sprays, but then it started getting stuck. Very aggravating! I tried moving the head around and I even took the head off and put it back on, but it still gets stuck. Oh well. You get what you pay for, I guess.
