It is popular for using the whatsapp on the laptop or pc.First time I have heard about it about two years ago.From then I am using it frequently while using my laptop.one thing I must say about this site that it must need modification beacause there is much more disadvantage in this site like you cannot place a video call from this site, your phone and laptop both should be connected to the internet, anybody can hack your whatsapp within 10 seconds and misuse your whatsapp account, sometime there is problem in scanning qr code.apart from this there is a;so so much advantage of using it like it is easy to use than mobile, if you are using your laptop or pc you neednot go to mobile.Time to load the content is quick and its service is very good. iw ill recommend to everyone but be careful from manual hacking of your whatsapp account.
