I'm reviewing Metromile as a third party claimant and my experience.
Time is of the essence they say well not here. My claim was finalized two months later, yes it took two months. It took them over a week to get my vehicle out from the tow truck company's yard, it incurred thousands of dollars in storage fees, not my problem, it was their insurer that totaled my car.
It seems like their adjusters are trained to be extra slow. On top of it all, I was charged for my car rental and had to deal with another nightmare trying to get my money back from them. If you're ever in an accident that isn't your fault and the other party has Metromile, I would highly advise to go through your own and have your insurance deal with them.
