I have bought these cases for my phone for the past 4 years. Starting for the HTC 3d and now the HTC ONE. The cases have been through alot i mount my phone on a bike mount and use it for video on my motorcycle. I've wrecked 2 times with it and had my phone bounce across the road and i was going at least 60 mpg. No damage to the phone or the case. I did have some problems with the tabs when i would take it apart to clean it the tabs the bottom half broke. Due to this problem when my phone fell off a roof the phone bounded out after it had already hit the ground still protected the main fall.
I emailed the company they asked for pictures of the case and the issue i was having and they sent me a replacement case. great product just bought again for my girlfriends s4.
