It works well for me but has a learning curve.
This is a very important tool for those of us that have a heart symptom.  It came on time and works well. It may take you some time to learn it's system. The manual is very important to get the results you want. The windows 10 iso. file installed for me. I can upload a reading to the computer, view it, print it, scan it to a jpeg, and email it to my doctor. Yes that's a round about way but It,s better than just telling the doctor what you experienced. I use the "Limb" setting with two leads above my ankles and two above the wrists. This gives a read out with thee lines instead of just one line.  For the price it's the best ECG available that I know of. It's not like have the doctor do it. You have to learn it's system but it is worth the effort if you want to have your doctor view what is going on when you aren't at the doctors office. I see some complaints but hope it keeps working for me when I need it.  Best wishes to all of you!
