Okay got tired of waiting and decided to give a go on the screen protector. I watch the video and the first installation was a disaster. Watch the video three more times then tried again. Now it's a tad crooked on the button alignment but there are no bubbles!

Not going to try again. I will save the last one as a replacement I would defiantly get
these again.
No degradation of quality. It's truly is nearly invisible. If it was on straight I wouldn't even know it was there.
I then installed the
new case and it's not one I would buy again. It has two pieces and the first piece is soft rubber, too soft and does not fit snugly enough for me. The second piece is hard plastic and I like that part. It could be a great case if the first piece was made of stiffer material like TPU and fit snug.
