Sold me a screen protector for 50. Galaxy s8 plus. It's terrible Ive went through 3 in 2 months. Won't stay on. They won't get me the glass curve elite and want to continue to charge me 10 dollars for an "installation fee" said ok I'll install it myself then because you and me both know these protectors suck. Wouldn't do it. I bought 2 glass protectors off Amazon for 10 dollars 5 a piece. They work 10x better. I DO NOT RECOMMEND GIVING THESE GUYS YOUR BUSINESS!!!
