I have had good and bad luck with refurbished electronics. My Dell Inspiron Laptop was $650 refurbished and purchased through the Dell Outlet. After 6 months have had no problems, but whenever I get a glitch I do wonder if it is a glitch I would with a new computer or just a refurbished one. But overall have been very happy. And the laptop came with a factory warranty.
On the other hand, I purchased a Logitech wireless keyboard and mouse refurbished through Overstock and had all sorts of problems. I could not get either of them to connect with my computer, so I called a Logitech specialist and they asked for the ID codes on the bottom of each item to help with the troubleshooting. Both had been scratched out, so it took even longer to troubleshoot. Guess when overstock refurbishes they have to scratch out the ID no. Finally the technician concluded that there was likely a problem with the receiver so he would send me a new one even though he didn't sell me the keyboard or mouse.
My conclusion, from now on I will only consider refurbished electronics sold directly from the manufacturer. Feel they will be more accountable and know their equipment better.
