I would give zero stars if I was able to. This company is a horrible and the customer service is even worse. The two sensors I had, one stopped at 9 days of the 14 days and the second lasted 7 days of the 14 days. I called to get information from the company as to why they keep shorting out and they have no answers as to why. They will not replace the product unless you ended up in the emergency room do to their faulty product. Luckily my son didn't end up in the hospital or emergency room. *I already called that number and was told that nothing could be done. Your answer is to save face. Still a zero out of five would be my response.
