Query: Total waste of money

Save yourself the hassle and just take a fifty dollar bill and throw it in the garbage, because that's really all you're doing by buying this piece of junk. I've had this thing for just over a month, and it doesn't work anymore. I've kept the device clean according to the instructions, and have removed the water scale from the reservoir, yet each time I fill the tank and turn it on, the low-water safety switch immediately shuts it off.And good luck getting any product information from the Bionaire web site.
