So I generally like my Garmin Vivosmart HR. I'm surprised that I don't look at the data (sleep and heart rate) as much as I thought I would. I really like the smart phone notifications.
But, if you are interested, this is a great deal. I paid $130 for mine, so this saves you $30.
The links above is for the non-GPS version. For a running/GPS solution, I must say I am extremely happy with my Garmin 235 GPS watch. It would be close to being my single device solution except I don't think it would be as comfortable to sleep in.
