I recently bought a refurbished 3D printer from Technology Outlet, which was stated to have been tested and I assumed, ready to use. The nozzle wasn't cleaned and was clogged with dried filament and there was filament already in the feed tube. I had to then find a guide online for how to clean the nozzle etc and get it ready to print. The power cable/instructions/tools were all missing, which is apparently to be expected on a refurbished machine. Its all printing well so far but its a bit of a shame that was the experience, as I don't think it would take much to follow up a purchase of a refurb'ed printer with an email from Tech Outlet with a link to where to get the manual, the software, the tools etc which would have made things better in my opinion.
