Product arrived ahead of schedule and was as advertised. I have intalled it and used it for a week. Touch and clarity are great. No mars on the surface. Can't vouch for the drop factor yet, but I'm very happy with the product to date. The application with the hinge strips didn't work as well as I would have liked. Next time, I'll just turn on the screen and align it with that. What looked like a small bubble or dust spot that was persisting upon application was gone the next day. Good value. Very happy so far. Would use again.
