First of all is you will need to have Whatsapp to be installed on an smartphone and that should be connected to the internet. The steps are super easy. Just scan the QR Code from the website and go on. You can chat, see status, send documents. The user interface is pretty clean and handy. Works with Microsoft Edge or Internet Explorer. The things tht you cannot do is whatsapp call and whatsapp video call which is a bit concerning. However I think they should try to bring those missing features in the future updates. Overall very useful and I usually use it when phone is having very low battery and is charging. It also shows a notification to charge your phone when your phones battery is low which is pretty cool. Overall I like using it!
