Mate. I don’t have to think about it. I know what an ECG is (the clue is in the avatar) And this is a HRM at best. Anyway. Value is an objective thing. And if you think you’re getting good value with this (cough) ‘ECG Machine’ then, that’s the main thing isn’t it?. Cheers!

I suppose we'll just have to disagree. I've built primitive versions of this tech myself (anyone with basic electronic skills can, really) and its good enough to show unusual QT intervals and PVCs. I wouldn't use it for diagnostics, but it's certainly more than a heart rate monitor.

And how many of those are hand me down iPhone 3,4, and 5 that don't run IOS11 and above required for the Watch 4.


Most of them. Well over a billion. Apple's latest OS supports all the way back to the 5s and Apple sells 200-250 Million phones EACH YEAR. You see there's not a lot of people running around with iPhone 3's and 4's. Probably close to zero when you can buy a refurb 5s for around a hundred bucks. LOL.

Now your next point.
