This auction is for a USED set of 10 Microsoft Surface RT. All of them turn on and have been factory reset. One of them has a cracked screen. It works but there may be some issues using the touch portion of the cracked area. There are no guarantees regarding the battery life of these machines, however all seem to work when plugged in. In one of the pictures, the cracked one had not yet been reset, but it has since been reset. All of these items were used in a classroom and have only been turned on and reset. There appears to be no issues with these machines, however they are sold as is. All of them come in their original box with their original power supply nothing else. I do not know anything about these as they were given to me. There does not appear to be any major dents or scratches on the exterior other than the one with the cracked screen and normal wear. Only tested by plugging in and turning on. No further testing was done. No returns accepted. Buyer understands that these are sold as is with no guarantees. Sold as a complete Unit.
