I ordered a kit to replace a Samsung Note 10 Plus battery. The kit was nice and complete, but they sent a used battery. I complained and they told me no, the battery is new. I sent pictures showing the dents in it and adhesive. It was clearly pulled out of a phone. Since they wouldn't send me another battery, I installed the used one. It lasted about 3 months before it wouldn't hold a charge anymore. So, I got screwed and had to order another battery. Hopefully this one is not used like the last one. I would seriously think about getting parts from some other vendor. Ebay is full of people selling parts and the videos of how to do the repairs are available on youtube. So, no reason to ever buy anything from ifixit in the future.
