Title: Does not last long
Review: I bought one of these to put in my snakes tank on a timer. It worked well for a couple weeks, then stopped working completely. I cleaned the little disc and soaked the unit in a vinegar/water solution, but it still didn't work. I ended up throwing it away and wasting my money, not sure what the problem was.If you can get this to work and stay working, snakes seem to love it. Mine liked to sit near it when it was on and drink the water droplets that collected around her mouth.
