We were provided the Bump Armor CB Slim Hard Shell case by Nevada school system. They promised it would protect my son’s Chromebook, but within a week the zipper started to stick, within a month the zipper broke and my son stopped using the case. I tried to reach them on the bumparmor.com, but they have NO PHONE, NO ADDRESS and NO EMAIL. . I reached out on Facebook and no response, terrible customer service, seems they just don’t care about the kids. I had to purchase, out of my own pocket, another Chromebook case. I reached out on I spoke to some other parents in the school, and my experience was not unique. Most of the parents said their kids stopped using the Bump Armor case.
