I'm posting my review here because I don't want to contribute to the flood of separate review threads that are popping up and cluttering up the place. This is copied and pasted from Amazon.

This is a battery case, so you should know a few things going in. The most important thing is that it's huge. The case easily triples the width of the phone (it's thicker than the renders in the product description make it look) and adds about half an inch to the bottom bezel. It adds a good amount of weight to it too. Also, NFC (and therefore Android Pay) does not work through this case. Both of these issues are common sense, and I did not factor them into my rating.

PROS:
-Battery life for me from 100% phone and case to 0% phone and case was 4 days and 8 hours. I used my phone normally, which for me means social media, chat apps, email checking, web browsing and the occasional game.
-Data transfer and squeeze functions still work as advertised.
-The volume and power buttons have a nice feel and work well.
-You can charge the case separately from the phone.

CONS:
-The USB-C to headphone jack adapter included with the Pixel 2 XL does not work with this case. This is a huge drawback for me. If I'm going to strap this brick to my phone, it will probably be because I'm traveling and if that's the case, I'll want to listen to music. That's not possible with this case unless you have Bluetooth headphones.
-The phone is secured tightly along the top and bottom edges, but the side edges are not tightly gripped by the TPU layer of the case. Although I did not perform any drop tests, I would be concerned that the case would not hold my phone tightly in the event of a drop.
-The TPU layer is very thin, and I'm not confident about the protection that it would give during a drop.
-(Not necessarily a con) The case does not quick charge. It charges at the same rate as a 2.4V, 750 mAh usb 2.0 port. That shouldn't matter since this thing will be theoretically permanently attached to your phone though.
-You have to hold the power button on the back of the case for 3 seconds before it will begin charging your phone. It's a minor annoyance, but an unnecessary one in my opinion.

CONCLUSION:
I personally would not buy this. If you're spending $900 on a phone, a good portion of that premium goes toward the design of the phone. Why would you cover it up with this brick of a case? If you're going to do that, just buy a lower end phone with a larger battery for less than half the price. However, case-biases aside, the lack of headphone adapter functionality is a deal breaker for me. If you need a portable source of power, just buy a portable battery that supports USB power delivery (quick charging).
