I got a Mblaze WiFi dongle three days back(14/09/2014)-8459970236, it was a tough task to get it activated and verification process was the time taking. Once activated the device which says 9.8 mbps max speed but it hardly touches the speed of 200 kbps, and when you call customer care and retailer they hardly take any responsibility to sort out your problem.
Customer care executive says the are in which you stay(west patel nagar, Delhi) has some network problem and the retailer in same area(U-47 west patel nagar) using his device shows the speed of 5.9 mbps as a demo test!
when the compliant is registered some technical department person comes from retail store and feels sorry for the speed and asks for another 24 hours to check the problem, and says "bhaiya whats my problem if there is no speed"To the Service, Retailer, and the network provider I rate them 1/5.
Seriously its worst.
