I have been using "dell Inspiron 3455" for last 4 years .
The smoothness is amazing ??.
Still after using it for 4 years continuously i get 5 to 6 hours of battery backup 4 years back it was upto 10 hours which is appreciable.
Problem i am facing:- Though i use my laptop with a laptop stand the problem is facing t it's screws are coming out one by one unnecessarily I have to tight it all the time .
