I have bought several laptop psu's during the last 2 years and this is by far the best quality I have had. Some in the past from other sellers have suffered cracked cables after only a few months. The cables are of a decent quality and thick, the supply doesn't get too warm and the connectors are of good quality. All this might depend on who the seller is but the one from Laptop Solutions London is top class.
Easy to load up your music, simple to use but remember to set the region to rest of the world for louder volume than Europe. The display can be hard to read if your sight is not sharp but a pair of glasses and all is good. Battery life is good but you can't change the battery so make sure you keep it charged up.
