I brought my iPhone 5S to this place (it's about 40 mins away from my house) because I had cracked the screen. They charged $100 (talked down from $120). They told me it was an original "factory" screen. I left and when I got home I peeled the plastic off and there was a dark square shape on the screen. I tried to clean it but it was actually in the glass of the "original factory" screen. I took my phone to apple and they immediately said the screen was a really cheap after market screen. Don't waste your money in this place!!! I'm really disappointed.
