Title: Gave Up after 4 Units
Review: I've tried 4 different units (3 sent free by the manufacturer after my original purchase). All worked fine at first, but then the sprayer and/or the ultrasound device on the wand stopped working. They were kind enough to give me a full refund after the fourth one failed.
