With the Pixel 2 coming out I highly doubt they will make one for the smaller original Pixel.
I bought the one for my Pixel XL and not super happy. No lip for the screen so it lasts on the glass front. The wrist part is the case I'd activated by pressing a button and holding it down for 3 seconds and it activated all the time in my pocket accidentally. So now I see my battery is about 50% but the mophie battery was already being used while I used the phone.
