Query: Terrible product

If I could give zero stars I would. We bought this model, plugged it in, set it to 24/7 mode, and waited. And waited. The bulb never came on so we exchanged it, thinking it was defective. Got second one home and same thing. Only by accident did we discover that the switch wasn't covering the sensor enough to turn on the bulb. It only worked when duct tape was put over it. And by "worked" I mean the bulb came on. We chose not to use the chemical lure provided and I don't think a single bug went near it. We'll be taking this back for a refund and likely ordering a Flowtron.
