Good product but very hard to install. Samsung has designed the keyboard to be non-replaceable. Not only you have to rip apart the whole Motherboard & Screen out, but front bezel too. Now old keyboard is having tabs melted into the front paneling. you have to melt those tabs out and put new ones in. Then you can play with solder to try to melt new tabs.
I could not install the product yet but saving it for another day.
