The only thing good about this is that it works sometimes and the price isn't super terrible. I like that it has a lot of memory and the instructions are kind of on the cuff but the cuff is too big for me someone with a small wrist. Sometimes it doesn't stick and when it's taking your blood pressure it comes off like loosens up and it doesn't read your blood pressure properly. I have a rural run on it to keep the back closed because it falls off sometimes it doesn't say.
