I needed to replace the back glass on my Google Pixel so I turned to Amazon. Different listings for, ostensibly, the same product. Wildly conflicting reviews. Various sellers who may be selling the listed product or a cheap knock off. Were the negative reviews due to an interior product or user incompetence? I couldn't determine who to trust. I turned to ifixit instead, and wound up with a lower price and the relief that comes from dealing with a known seller. I can't tell if the glass is authentic (not without trying to break it), but it installed easily and looks perfect.
