Bought the unit this Thursday and updated the software to 6.16 immediately. Now, just two days into my Instinct 2 Solar and so far four crashes resetting steps, stress, body battery and sleep. I didn't realized it was a brand new model and after my experiences with previous brand new Garmins (610, 630 and 735XT) I should have known better - my bad!
Like my previous experiences I guess I'll be happy in another 9-12 months.
