Shame on paypal for even taking this goon seriously. I sold him and 11/14 upgraded F75, he saw some bad reviews about it, and demanded a refund "ASAP" as he stated. Those funds we're put to a new machine for me, so I told him wait to receive the machine, and he can see for himself it is amazing. That wasn't good enlighten, so he opened a case. I'm warning each of you, he is a pain!
