Selling this as we bought it for our old laptop and no longer need it since getting this one. Im just going to write down what it says on the box as I have no idea about computer things!
External super multi dvd rewriter
20 x dvd R write speed
8.5 gb Dvd+R double layer 16 x
Dvd-R Dual layer 12 x
Theres a sticker on the box that says pre owned but we've only just seen this, we bought it new from pc world. :/ We've tested it once but not actually used it. Box is a little tatty. Postage at cost, courier probably best as its quite heavy. :)
Now 20 plus postage.
