I have bought a few chargers in the year I have had my laptop and none of them seem to hold up for long. Part of the problem is the prong doesn't actually fit all the way into the laptop so they get bent easily. So far this one has held up nicely and the prong fits nicely. I am giving it 5 stars and will update if it breaks but for now it seems to be one of the better ones I have bought so I have high hopes!
