Epix gen 2….an epic fail

Anyone have their back button broken after 1 swim.
For context I purchased a Garmin Epix gen 2 in April to train for my Ironman 70.3. First time taking it for a swim in salt water it breaks 1 MONTH FROM the race. Garmin thankfully replaced it. 2 weeks after that replacement the same thing occurred. I thought fine Garmin will replace this one PRAYING it will come before the race. But no, they refused to replace it and all they could offer is a refund.
The issue with this is now not only am I watch less right before my race but I previously bought my Epix gen 2 on sale, now they don’t stock this watch and I’m forced to shelf out hundreds of more dollars to buy the newer model. WHICH WILL LIKELY BREAK AGAIN. I have spent 6 months relying on this watch for training and now for the race I can’t use it. Do not buy this watch if you plan to go in salt water
