After a few days living with a Microsoft Band…
I have worn a Polar s610 heart rate monitor as my watch for years (probably 15+), as I write it needs another battery swap, which means sending it to Polar, something I have done a couple of times in the past for servicing The batteries in the watch last 5 years or so, in the associated heart rate monitor strap maybe a bit more depending on usage. The point is I am used to having a device that ‘can’ give heart rate information, it seems normal, but I do need to remember to put on the heart rate strap, something I would only usually do for a race or specific training set....
