1byone Portable Wireless ECG EKG Monitor Home Monitoring Devices for Health Care Use, Heart Rate Tracking Monitor, App Support, iOS & Android Smartphones (PC Software,Both Windows & Mac)

You probably bought this thinking it would record 30 seconds. It says it will on 1 by ones’s page here on Amazon. That’s because this is the PM 10 not the PM 30. No place on the page does it say which model it is and they even doctored the picture that would have given you an idea of what model it is. The PM 10 is about $40 less than the 30 second PM 30. My PM 10 stopped working after about 30 days and was returned. I made sure Amazon Customer Support knew the web page was deceitful. This model is also marketed by MKAY, CONTEC and others who correctly identify and tell you it is the PM 10. While it worked it worked well as did the app on my iOS devices.

IT APPEARS THE APP HAS BEEN DISCONTINUED AND NOT REPLACED NOT A GOOD SIGN, SO, THIS MONITOR HAS PROBABLY ALSO BEEN DISCONTINUED, STORY OF MY LIFE. AFTER ALL IT WAS CHEAPER THAN ALL THE OTHERS, SO I WILL PROBABLY BE BUYING A BETTER ONE IN THE NEAR FUTURE, BUT I HAVE FOUND THAT I CAN GOOGLE THE DIAGNOSIS AND STILL BENEFIT FROM THE READINGS, I HAVE FOUND IT TO BE VERY HELPFUL IN THAT MANNER.

This is a cheap Chinees knock-off of a real medical device. Does it work? Sometimes. Is it user friendly? Absolutely not. --- This seems to work at random and is extremely finicky about having the contacts clean. It does give you (when it's working) a EKG output that's transferable to phone or computer but getting a clean scan is tough due to the contacts and the unit's size (it slightly smaller than a credit card) which makes holding it steady with good contact a bit of a chore. Would not trust this unit's info to make medical decisions. I bought it as a trial to see if it would work for an aging relative and she was unable to hold it in place long enough to make a decent trace. I've tried it and not had much better luck. If you're in serious need go to one of the more expensive units.

It works better than I expected. I do wish the rhythm strip would last longer than 10 sec each. It is very light and the battery lasts a long time.

I love this little thing. It's so convenient and it came in handy when my boyfriend started talking about chest pain. I would definitely recommend.

Good Value

This is a good ekg machine, but not great. The rhythm strip shows a lot of interference no matter how we hold the machine. When it finally calms down, the rhythm strip stops.

Acts as a guide
