I have bought several Amazon Refurb items.
I have to say I am very impressed with them all so far.
I bought a Mk2 BT Vision PVR that was to all intents and purposes brand new. Still had the clingy film all over it.
Bought 4 Dell i5 Optiplex desktops that were at least 4 years old but looked brand new. Also had SSDs and 8GB of ram for under £300 each!
Bought a Dell Latitude i5 laptop that was a 2012 model and was perfect but for the two thin rubber feet were missing at the front. Again cheap price.
