I will NEVER and also others that purchased from zagg do so again. Bottom line their products are just HYPE I am not saying they are bad just no better than others out there and not worth the price at all.
I have purchased many screen protectors for my 6 and 6 plus, the ones I like best DO come from amazon.
Tech Armor tempered glass is just amazing, I am using a cheaper brand at the moment, but I installed 2 Tech armor's on 2 6 plus's and they are outstanding. I have also used their film and it is also just outstanding for price and quality.
