This product is one of the biggest piece of crap in medical history. Its readings are always way off by 150 unite or more, causing the patient to take the wrong dose of insulin. If you call and ask for help, it is always the patient's fault it is not working. I've been using it for a few years. It used to be great. Now it’s just a joke.
Bottom Line: No, I would not recommend this to a friend
