Having purchased several ‘refurbished’ items in the past, I found this to be very dirty. Sand on the keyboard, lint between the keys, literally dirt on the cover and power adapter.I spent 15 minutes wiping it down but needed to remove a couple of keys to get the dirt from in between…. When I removed the space bar I decided to stop and just return it (to much lint ‘sand’) I didn’t even plug it in as it was filthy.Realized I would not even use it as I intended (to run some back up programs for laser)Too bad other reviews showed promise…
