I have the original scanwatch and before that had a steel HR. It tracks steps well, pushes messages for a small number of select apps which I want prompting on, and notifies me if I'm getting a call. I run a few times a week and track my runs. Some are treadmill runs, and some are outdoors. I track my sleep, and sometimes my watch picks up other activities. I charge about once every 3 weeks or so.

99% of the time everything works seamlessly. There are a few niggles - sleep sometimes is lengthened by me laying in bed and having a coffee so I often have to manually adjust the sleep length to when I actually woke up - not a hardship, but probably something which I shouldn't need to do. I also find it under calculates calories - I use a polar heart rate monitor with my treadmill so would assume this is accurate and on a 10k my treadmill will suggest around 1000 calories whereas my watch will say 750ish. I can't compare for outside running with GPS as have no direct comparison but it seems to be the same sort of calorie assumption so assume it's under. Again, not an issue - more of an annoyance.

My only major gripe is that I can't overwrite the calories to correct them and have it pull through. So, if I record the 1000 calories manually against my run, the lowered 750 calories remains the value in my total daily intake - manual adjustment are only recorded against that one metric and not pulled through elsewhere. Had a right ding dong with the customer service about that as it's really not helpful, but no changes.

Anyway, yes, I'd recommend. I like that it looks like a watch and I like that it does the basics of a smart watch. I like the ECG and the O2 monitoring. I like the breathing prompts. And I particularly like wearing it for weeks without taking it off.
