Hard to evaluate the product in time. It has been just over a month I have, it works. I shall not say the life it will have. Regarding the charger itself, I plugged in a laptop Samsung R530. Amazon gave it as compatible and that's what it is. It does not heat more than the old diet. However, the tip is thinner than the original charger. It therefore falls perfectly into the socket, but there the game. It does not create a false contact, load it constantly so I'm satisfied, but this game is that there is an increased risk of breakage of the socket. That is why I will not put 5 stars, I would have preferred that the cap fits perfectly.
