My Experience :
1. Order zagg full body.
2. Received it after 2 weeks.
3. Install 2 days ago, Package was well packaged, I got it with a little spong, not the spray, not leaking, all ok.
4. Install went perfectly smooth, no need for heat blowers fans fire smoke or beer.
5. Applied solution to the shield, a bit to the phone, carefully located the shield on the phone, squeegied the solution and bubbles out while soaking them into cloth.
6. No bubbles, phone looks good, most stickyness went away after 1 day.
7. Touchscreen : Still responsive, still looks great - Yes it changed a bit but I cannot say it's for worse.

Ultimately this thing did make the phone looks a little cheaper, but I rather it looks cheaper, then expensive with ugly scratches all over the place.

Bottom line : I'm happy I purchased it, and i'm keeping it.
