Query: not good at all...save your money for a different one

I purchased this for my Sony Vio. It worked but only for about a 1.5 months. The electrical end that plugs into the outlet cracked near the supply but it still worked. Then the unit stopped working totally. I checked the voltage from the cord to the outlet and there was 120V, so the power supply itself has failed after not a lot of time. Hopefully they will replace it. I'll keep you posted.UPDATE: You only get a 1 month return on this item. Don't bother to buy it. It is junk!!!
