Bests & Worsts Reviews from Amazon

I was using this for a couple days and was getting very low readings. I had others in my house try to use it also and then we used a manual and another machine. This showed three of us to be about 20 numbers lower than the other cuffs we used. The other cuffs read more accurate to what our actual blood pressure was. The fit was good and it was easy to use but lack if accuracy was a concern.
