They are a scam, DO NOT CALL THEM. They will send you a fake delivery notice. You end up calling the number and the guy will tell you its for a TIDE bottle and asks you a bunch of personal questions. He then tries to schedule a home test that they will perform to check your water. Probably to see what exactly you have in your house and plan a robbery. Don't fall for it. I'm blocking the number and any other numbers he sells my number to.
