Yes, I would like to know people's opinions on the Zagg. Lifetime warranty sure sounds nice!
Here's another recommendation for Zagg InvisibleShield products. They are all on my iOS devices (as well as my wife's and her families) as well as my company Surface tablet. Their warranty is great and customer service as well. (I know this is screen protector but LifeProof was also very helpful. Ordered new case for 6s but it shipped without the headphone adapter. I called and they didn't have any in stock so they shipped me a whole new case and told me to keep the one I had as a backup for free.)
