I have to say after using UAG on several phones this UAG case for the Pixel XL is clearly a rush job. Both my Spigen Rugged Armor, and definitely my Incipio Octane are much better quality cases.
The UAG has several flaws. First the phone usually finds it's way out of the case at one corner once a day. Doesn't feel loose but that repeated action doesn't lie. Next the top and bottom on the front show some of the the metal and looks almost like it just wasn't quite formed correctly. Being this way isn't a big deal, however it also let's you see light under the lip on the case through the headphone jack hole. It's like the hole was cut way to big or the lip wasn't formed correctly on the top. Then onto the next and more frustrating issue for me. On flat surfaces it doesn't lay flat, and teeters. Really annoying if you are trying to type while it's on a counter or a desk. However the most damaging issue to the phone and what I think is tied to the way it must be not fitted perfect and somehow loose is the fact that every other day dust and dirt is inside the case rubbing on the phone. Not good. Big concern for me further proving it's not a tight fit. Finally the back quality, the glossy parts scratch in pocket, and the little rubber lugs are very flimsy and move and snap if you rub them wrong.
I verified this with my friend who has the same setup just different case color. Same problems with it on his Pixel XL. Again I can't believe this with all the times I have used them in the past it is sad how the rushed non quality feel of this case is for the Pixel XL. Not worth the money if you ask me.
