Not worth purchasing.
Not worth purchasing. Nothing breaks until the insurance is expired.

Get the INSURANCE!!!!
My chair broke. Almost at the one year mark… I’m so glad I got the insurance! I put in my claim (it was easy) and it was resolved within 72 hours. Sometimes I decline the insurance because it turns out to be more hassle than it’s worth but Asurion came through!
