Brought this for wife works great will take to my doctor's office the next time I have to an EKG to compare the accuracy

Very easy to use , easy to install , fast accurate work

This crap stopped working 6 months after I brought it,

For EKG, it's a miracle to be able to use this at home,, and the work it does.

Excellent - worked right out of the box as stated, connected easily to the app and I got my readout 10 minutes after taking it out of the box

It has been working great for 6 months

Product works very well and would recommend.

This works well with my iPhone XR but not with my iPad

So far it seems to be working well.
