When I first got this MacBook, there were scratches on the laptop, but those scratches (major and minor) didn't bother me. The performance was good for first few weeks, but the laptop started running slow after few weeks. In July, I started my summer school and had to do some light python coding on google collab and the code ran very slow, and often stopped responding. I also tried to use Jupyter for coding and the software would work very slowly. Recently, one of two USB charging ports also stopped working.With all these complications, I wasn't satisfied with this MacBook and tried to return it and get a replacement. The seller told me they can't replace the laptop which was a violation of Amazon 90 days replace, return or refund warranty. I tried to return it and the return code they gave me was not valid. The employee at the Amazon locker hub told me to cancel the return and reprocess the return to get new return code. I told her that this laptop is outside the return window and I wasn't sure if I cancel the return, they would reprocess the return. The employee told me that if the return code is invalid, they will reprocess it. So I went ahead to cancel the return. The seller denied to reprocess the return and told me I can no longer return this. So, I filed a claim with the Amazon and the Amazon also denied my claim saying that the item is outside the return window. Now I am stuck with a MacBook that doesn't work properly, runs very slow and has a damaged port. ABSOLUTELY HORRIBLE EXPERIENCE!!! The 90-day replace, return or refund warranty on Amazon renewed store is just a scam to lure people into buying laptops that are going to stop working in a few months and they DO NOT fulfill their warranty terms either.
