Have one with XLqb (quite black) my impressions:
(1) It took a day to mold to body, at first I got contact bubble on the top glass part that looked like little "oil spills" probably due to too tight a dit and contact to glass screen top on back
(2) The clear top shows excess micro scratches on the case either due to manufacturing or just its too glossy ... You see this more indoors under lights
(3) There's not much protection - it's a hard case, no cushion, and very slippery almost more than a naked XL
(4) The bottom lips force your finger over the speaker if you hold the phone in your right hand, one handed which revealed that boy the Pixel does not like getting its speaker covered because it didn't just muffle but really distorted the sound when at full volume playing Pink Floyd (maybe I need to listen to something from this century).
Overall I ended up buying the Spigen off Amazon, I doubt I will be using this case long.
It shows too much in terms of dust, dirt, scratches easily it appears, and isn't BPA free so you get the funky gas-glow when tilting and holding it in sunlight.
