I looked at getting it for my P4 as the cost of a gimbal replacement alone would justify the $260+ care package. You still have the warranty provisions considered under Australian law but not for throwing it into a tree due to a mistake on your behalf. I've read their glossy overview of the plan and it looks promising if I were running a small business using my drone but I'm not sure if that's excluded or not.
I decided against it and have not had a spill in the ten months I've owned mine and don't intend to, if it happens, well I'll get another one.
