I use this from last 3 months, such a great perfomance, it also easy to carry anywhere you go, thin stylish, battery perfomance is very very good, not a single prblem if you used it untill 8-9 hrs. I used it daily about 8 hrs, no a single hitting problem found . once it fully charged, it needs 5-6 hrs to empty if you use continously, also nice service support by dell . thanks to DELL. Keep going. all the best.
