It is very good tool to waste your hard earned money as they are not professional, they are just playing with our time and money.
I have tried this website only once and due to its pathetic experience I will never use it.
They do not know the word called "Customer service" and "customer satisfaction" and "Trust".Once I ordered Sony power bank, and they sent me MI power bank. when I complained about it nobody is bother to listen my complain and every time they disconnected the call without any reason.
