This is the one of the oldest and trustable company .i buy this laptop at 2014 still using but there is no problem in this laptop still now.battery backupo is very impressive, and parfomence? its too fast than u can imagine. its very user friendly.very light weight.and totally handy.Come to think about it I am using this product more than 2 years and I can surely tell that I am fully satisfied. its not a waste of money but also its a good product in this price .sony service center is very close to my house and its servicing is greater than I imagine.
