Lenovo g500s model is an amazing quality product in cheap price.When we talk to the lenovo brand at first we focus the sound quality . Yes, DOLBY audio in inbuilt in this model & its sound quality is great.This laptop’s performance is also good.Its processor is very good quality.If u compare with this model to others model & band it’s storage capacity is large.In market the product is available in i3 & i5 also. But I prefer i3 is best in this price.Now goes to specification 1) 15.6 inch HD led display. 2) i3 4th generation intel processor. 3) 1 tb hard disk. 4) 2 to 4 gb RAM. 5) Also inbuilt NVIDIA graphics.
