I also just recieved the Omoton case and I am very impressed with it. The cover lines up perfectly with the rim and it looks to be sealed in. It fits like a glove and is featherlight. The auto wake feature works perfectly. It's exactly what I want and am looking for.
It definitely looks to be durable. I actually disagree with Fbone - it's a strong shell case, I think it would take very heavy objects to bend the cover. The lid completely seals the device except for the usb and power button hole. IMO, the biggest danger with shell cases is coins or other small objects sliding into the gap between the cover. I've had thicker cases with covers, that are not as well designed and that easily can be pushed away from the rim. This case is well designed and does not allow for that. I trust that it would hold up very well in a backpack or suitcase.
This is my fourth Omoton case(three others for my kindles) and highly recommend it. My kindles have been well protected through a lot of travel over the last year using the cases.
