First thoughts are impressive. The build looks a good quality, with the screen echoing the flush look of the watch. When wearing it on the watch I was expecting it to be super bulky and utilitarian looking. My original intention was just to snap it on when working in the garden etc, to avoid scuffs and bangs.
But actually I've been really impressed with the slimline nature. Yes you can tell there's a case on the watch, but it's not super obvious. So I'm going to wear it all the time.
The case comes with a peel off film on both sides of the glass screen, and packs of wet and dry wipes to prep the watch first. All very simple and pretty impressive.
I've included some photo's and videos so that you can see for yourself:
