Honestly, I wasn't expecting much. I mean it's a laptop charger. It's charges your computer, if it does that it should be considered good and on to the next great idea. I was impressed with this for a couple of reasons. 1) It's lighter than my original charger. So when I'm running around with this in my backpack it's nice. 2) It's so slim it doesn't take up much room, again fitting it in a backpack is great! 3) It solved another problem for me. I have an old Asus laptop that the powercord got broken on and with the swappable connectors, there was one that fit the Asus. Overall I would recommend this product. I'm not sure how it does with long term use, but right now I'm very happy with it!
