It worked fine for the first 19 months then crashed.  Investigation showed that the SS drive had stopped working and the computer could not boot.  Removing the ssid shoed me that this was NOT a Dell computer.  It has a no brands ssid, which Dell would not have used.  Opening this component up revealed that the memory chips were also no brand with no ID.  I will never again buy an Amazon certified renewed product.  I have telephoned the number shown on the computer case and was able to leave a message.
