This series of dell inspiron 3542 is very good in terms of performance however case covering of this is not strong enough but its ok.also display is good batterylife is good but one dark side of this laptop is their sound which is wave maxx audio its just below average I buyed a extra jbl bluetooth speaker for replacing speaker bcz I m fond of music otherwise sound is ok for normal use and it is best option in this price range I purchased this product because dell as name says it is trustworthy barnd in indian market and according to my budget and need this series was perfect for me.for gaming purpose it is ok its nvidia series ge force 820m is sufficient for normal gaming but one thing I do not like about this pc is there is only one ram slot so you have to sacrifice if you want to extend your ram.i use this pc very roughly even I keep this pc in sleep mode whole day but it is working fine right now I played lot of games on this pc but I never faced too much heating problem for 4gb ram games battery backup is 3hours if you see movie but for gaming it is less but overall it is worth for money.
