Aside from availability, the cost is going to be your next problem.
I had Comminsure years ago but the premiums (and rate or premium increases) meant ditching it after a short time.
Also check the details on whether the payout is indexed or not in the event of a claim, and the conditions under which a claim is paid vs you being able to do paid work.
It might be that in the event of a claim you can work a full time min wage job (and will be expected to) and those earnings may come off any potential payout. All in all, the entire product may lose some of its shine for you. Or not.
