Once good signal strength is achieved, the data taking and recording works well.

Doesn't want to connect with Ipad, an when it does, signal is weak and have to try 3-4 to get a reading

Pros- Compact, Reasonable cost, Gives algorithmic interpretation of reading, fairly easy to useCons-Constant weak signal even when placed right next to phone, finger pad is too small for larger hands, battery is next to impossible to get back in, NO directions on some of the functions such as "Inverter" (not sure if program is set as it should be), Have to pay $10 a month for data storage, Privacy settings with microphone and phone setting access is concerning

I have had some issues getting clear signals, but overall I'm very satisfied

It took 10-15 tries before it will connect and even then, the signal is weak

The signal is amazingly clear, you can actually see it cleaning (filtering) the data on the screen.

I cannot get a good signal from the device to my phone/app regardless of how close I put device closewt to my phone.

Then started getting error no signal

I would say as a screening tool for a number of disorders that present as marked distortions of the EKG waveform this device would be a good match, but anything subtle, I don't see it catching that given the signal/noise ratio

it has VERY unstable signal and connection to my phone

It wasn't a poor signal or intermittent signal

I paid the price for a new item and what came was a used unit!The back had scratches as if the battery compartment was pried open with a metal object

If I use my fingers, the reading isn't as accurate (I shake) as when I just put it on the left side of my chest with cell phone on top of it
