This is the first time to buy a used PC and I was a bit concerned. The PC was delivered on time and I installed Dell SupportAssist right away and updated all drives and confirmed the there was no error from Hardware Scan.Then I was trying to install my SSD that has all my documents, but there was no caddy inside. I contacted Dell Support to find the part number and they asked me to send bunch of proofs for the ownership and spent almost one hour. Eventually I was told that a quote will be sent by email. (I have not received it yet from Dell) I was very frustrated.Then, I contacted the seller through Amazon and I got the first response in a couple of hours and exchanged a couple of emails and I was told that the part will be shipped today. What a difference!!!I received the part today and my SSD is not mounted properly.Thanks for KARAVAN and keep up your great work!!!
