Query: Difficult for Seniors

I purchased the Omron HEM-670IT wrist blood pressure monitor. The description sounded easy and promising because I could record thereadings on my computer too. Just getting the monitor itself to workcorrectly was a challenge....you have to hold it in a certain positionto your heart for it to work. Seniors who have difficulty with armmovements will find this impossible to deal with as I did.Went right back to the older style which always works easily and quickly.
