Works as advertised.
Can be fooled by a very regular, slow flutter, but a soon as the flutter breaks up even a little, the EMAY correctly identifies afib. I have paroxysmal afib, which can be treated with pharma ("pill in the pocket" afib). I bought this device so I won't be fooled by slow flutter and stop my medication. So far, absolutely does the job.

these cartridges work great - not rejected by the printer like some aftermarket cartridges. great price, too!

Who can ask for more???
Lowest price and comes in usable bags, so you don't have to handle the charcoal - just rinse the bags and pop them in your refugium, filter or whatever. Plus, the bags are sturdy and zippered, so they can be emptied and refilled at a later date.
