Since I experienced a catastrophic failure of my remote 14 months into the game, fortunately still while my workers comp case was pending, I did inquire into the extended warranty of Boston Sci. Bought it. Cost was de minimis compared to the cost of the remote itself.
Given the pendency of the work comp case I mentioned at the time, thankfully the work comp insurance carrier paid for the replacement remote in full. My new remote is still working well over a year into the game.
I hope and pray your experience will be well and that you will find the information you desire; however, I would just spring for the insurance on the unit were I you.
Caring,
