Purchased this Acer Aspire5 laptop on Aug 2020.  Returned under warranty 11 months later for screen flickering that rendered it unusable.  They said there was nothing wrong with it, but when it was sent back to us, the screen no longer flickered.  Until last week, when the same problem started over again.  So whatever temporary fix they performed last July did not last very long. Upon calling Acer, they said sorry, out of warranty.  So I will never buy another Acer.  I expect more than 18 months out of a laptop, and this malfunction began when the laptop was under warranty.
