Epic Trackday Insurance: Has Anyone Been Paid Out / Filed a Claim?

I'm fortunate to live a couple hours from Watkins Glen and do trackdays there often. Insurance for the weekend alternates in cost-effectiveness seemingly indiscriminately between Hagerty and Lockton, usually $400-500 with 15% deductible.

Epic Trackday Insurance has been advertising with BMWCCA and comes in at $321 for a weekend. But I'm hesitant to insure with them without hearing testimonials of them paying out when needed.

Does anyone have experience with them please?
