Review: Great product!! - Great product comes with everything needed for the change.
Review: Inexpensive, easy fix - My phone almost exploded! For some unknown reason, the battery that was original to my Samsung S22 became swollen and caused my phone to fail. I didn't have extra money to take it to a repair shop or to get a new one so I figured I had little to lose trying to replace the battery myself. After watching a few videos, I was able to replace the battery on my own. Once it was installed and I was able to get a full charge on it (it came charged about 60%) I was happy to learn that it held the charge much longer than the old one I had, it lasted nearly two days before I had to charge it again! The only reason I didn't give it five stars is that the battery does get hot, hotter than the original just from normal use. So be mindful of that, the last thing anyone wants is an exploding cell phone!
