When purchasing the product, I was led to believe this is a product being sold by IBM. It obviously isn't. First and foremost, the AC Adaptor does its main job of charging so no complaints or issues there. Only issues I had, firstly nothing clearly states this product is a non genuine Lenovo charger, secondly when i recieved the product; I found the power lead did not fit the AC adaptor so was forced to purchase another. So just bear these issues in mind before purchasing.
