I got my k11 and e2e protector today and while I really, really wanted to like it I'm going to send it back. It looks and feels great and maybe it will actually protect from a 6ft drop, but within an hour of using it the screen protector had shattered right near the home button. Also, the bottom "sagging" issue was very noticeable to me, AND the buttons definitely do rattle.
Maybe I just got a bad case, I don't know, but for about $70 total it's just not worth it to me. I'm hoping that Thanotech does the right thing and makes returning both easy, and also hope they give me a refund for their screen protector. I could understand if it was a different brand but they advertise it as working perfect with the bumper. And before anybody asks, no, I didn't drop it or abuse it. I had it in my pants pocket for a little and then a coat pocket, definitely nothing that should have shattered the screen.
I will add here that Thanotech has some great customer service. They emailed me back within an hour or so of my request to return the bumper. I'm still going to send the k11 back but I'm going to let them mail me a replacement screen protector since they said a few defective ones were shipped out.
I wasn't planning on using their glass protector, I was only gonna buy the bumper on their website and add in the Ice Max 3D, but this bottom sagging really concerns me.
Some people here have mentioned they have no such defect, but I hate to play the lottery game with this case. However, it's the only bumper that I have researched on and found to be compatible with edge to edge protectors while still providing a good lip for lay-on-the-table design.
Damn the dilemma..haha
