I purchased this computer in August 2020.  Spent most of the first day loading my files and software onto the computer.  The next day upon booting up the computer failed.  The operating system would not load.  The screen remained black after the Acer logo appeared.  So I called Acer customer service and they could not fix it over the phone.  They further admitted this is a known problem with this computer.  However, Acer would not offer a refund or send me a new computer.  Instead, they offered to send me a shipping label and then once they received it back they would take 15-20 business days to repair it and send it back to me.  Obviously, a ridiculous proposition for a brand new computer.  So I called Amazon, and of course they offered a refund.I will not be purchasing an Acer product again after this experience.  I believe they are knowingly selling a defective product.  My experience fits into a pattern of similar experiences of this Acer computer model failing upon or shortly after the computer's first use.
