Hello,
I am a user of a Laptop/ notebook X553 M and I must say it’s an amazing product I m using over 2 years. I am really happy with this product. Actually when I bought this product I got windows 8.1 with this but then it certainly updated my laptop to windows 10. And I think its really doing fine.
The Size of laptop I have is 15 inches and I think that’s the best size one should have for proper utilization.
Secondly It’s not very heavy in weight so can carry easily anywhere.
But I must say that this product is very good only if you want to use it for your home.
