The S910 is more then gig worthy...don't let anyone say different. Depending on how it's used tings can happen with any electronic item on the market.....sheeeesh I remember having to change all the buttons on my G1000 years ago also!... doesn't anyone understand that a mere $1700.00 investment, etc, brings a profit to a pro gigger using it many, many, many, times over, thru the years so what's a little service once in a while IF needed? Treat your gear with TLC and it will serve you well.
Or you can carry around something like the G70 and pay your Chiropractor...your choice..
