I got tired of waiting for Samsung and other smartwatch makers to enable ecg functionality in their US product lines, and started looking into options to import a Withings Wear ECG watch (which came out last year, but has never been released in the US). For some reason Spanish Amazon has the blue band/white dial version on sale for much cheaper than other European Amazon sites. It comes out to less than 60 euro including shipping to the US if you choose the cheapest shipping option (2-4 weeks). I splurged and upgraded to the fastest 1-6 day option, which was an extra 6 euro. I downloaded the Withings app from the US play store, and it has this model available as an option to set up a a new device, so it should be no problem to get it working on the US even though it was never released here.
