The product is original charger by Samsung and I'm very happy with it, the first battery is already accomplished. The power supply itself is a bit warm, no way as a "hot" to describe, but this is perfectly fine. Plugs fit all 100% "no wobble and no rattling".
Now even in the end, the nice lady at the service of telephone TUPower was very nice and friendly, and eager to meet my customers satisfaction, which is your way, succeeded to 100% ... very nice and a big thanks again for the extraordinary grace that concerned know about;) !!!
Oh still conclude now really value for money for my feeling very well not going to better because it is original and not a replica.
Thank TUPower, finally I can use my laptop again.
