You get what you pay for
Easy to use right out of the box. Batteries included. Small size , Two in one where you can actually get your heart pulse rate and blood pressure in one shot in a matter of seconds. I like the large display which is easier to read. The green, yellow and red indicators are quick ways to see results. It has easy to follow picture directions but it It is pretty easy; just slip it onto your wrist properly and hit the 'on' button. I am unsure of the results. There was no certificate of accuracy in the box. You can tell that the box and instructions are converted Chinese due to phrasing. If I had it to do over again, I'd look to a different brand.
