The installation process went better than expected, with a perfect result. The packet includes a screen guide which gives a great result. With the bumper the overall protection of the watch is very good and sturdy especially for working outside. The one thing that is kind of annoying is the screen cover effects the sensitivity and because the bumper has a lip, it makes it quite difficult to swipe across the screen. At this stage I am satisfied with the negatives, because I need something with great protection.
