Fb lite is one of the best app to use at all time.first I will tell u about the main fb app its take too much space from your phone space when u go to application manager u will see its acquire more than 400mb within few week so its hard to use it on a phone that have 1gb/less RAM.instead of that fb lite is good u can run smoothly even the network is slow or its 2/3g.i m using from last one year or may b more.n I m really impressed with its performance n running speed.apart from that its a good app taking less space in your phone.
