I have the 310 and it seems to work fine. the only thing that is odd is that some rides don't upload to the phone. I used to upload to the phone and then from there to Strava.
Not a big deal really since I just track with my phone directly (Strava and Samsung Health).
Oh, it froze at -20°F, but that is expected from nay battery device. Works fine at 0°F and above.
