Asurion really came through for me when I had an issue with my Canon printer. The process was smooth and easy from start to finish. The only small challenge was finding a box big enough to ship the printer, but once I had that, I just attached the label they sent and dropped it off at UPS. They kept me updated by email every step of the way, and after inspecting the printer, they determined it couldn’t be fixed. The next day, I received a full reimbursement. Excellent communication and great service all around!
