See if you can get a Band 1/ Band 2 for cheap. I got my Band 1 last year for $80, and since MS has stopped production of Band 2 you should get it reasonably cheap especially if you have someone from the US coming over. As far as I know FitBit and Garmin both work with W10m, however, you will need to wait for a bit to be able to read notifications as W10M GATT compatibility is still being worked on (expected by year end)
