Note that the pace for run is NOT accurate and very broken. They have issued a software update about 2 weeks ago that was supposed to address it, but it did not. They say to just use "average pace" and well, yeah...no.

There are still issues with some auto shut-offs in bike mode and power meter drop outs.

It's a $500 swim watch for me right now. Sigh. I use my 310 for the bike and run and the 910 for the swim. Super bummed that it was rushed to market.

An example of the pace issue is that every second the pace will jump anywhere from 30 seconds to 2 minutes. If I do a workout with a target pace the watch will yell at me nonstop to speed up, slowdown, speed up, slow down. I am never in the target zone due to the jumpiness of the watch. If I wear my 310 and 910 the 910 will jump from 10:30, 11:20, 8:47, 9:50, 9:00, 13:10, 11:10, 9:20 (every second!!!!). And my 310 will just show 11:10, 11:11, 11:09, 11:10. It's horribly frustrating.
