Negative Positive
Title: Be warned: Not for the elderly or people with arm weakness
Review: Let me start by saying that if you're an average healthy person this is a fairly decent BPM. It takes fast readings, is easy to put on and store, and has a memory of the readings taken including heart beats per minute. The big problem is that the advanced positioning sensor is very sensitive and requires your arm to remain completely still at 45 degrees in front of your chest for the entire reading. If you cannot find the correct position it will not take a reading at all. If it starts to take a reading and you slightly move out of the required angle it will give you an error message. Elderly folks, those with tremors, weak arm muscles, or people who are fidgety may not find much use in this machine.
