My insurance company sent me HoMedics to monitor my BP with over several weeks...like 3 months. It is back under control, so I put it away. I did have a wrist model, but it did not work right. Do take what ever you decide to try to the Dr.'s and have the nurse check it against their BP machine. Good Luck.
I did lose some weight and adopt a cat for inside the house...Dr. had to drop the medication down a drop, for the first time in 25 to 30 years. A milestone for me.
