I have asked for a demo before buying Pro3. The sales guy was patient and I got speeds upto 5mbps. Only then I bought the connection a week ago.
I did more than 50 speedtest.net tests at Vanagaram near Maduravoyal. I am very happy with the results. Max speed was 9 Mbps and lowest was 3.5 Mbps. II have used the connection for last 5-6 days non-stop and I observed excellent speed.I have used Tata, Reliance 3.1 mbps, BSNL and Airtel fixed line broadbands at the same time. I am cancelling all and retaining Pro3 as I get 40gb at Rs 999/- at good consistent speeds.
I get Vodafone 3g speeds upto 12 mbps but they are expensive for 20-30gb usage. Thats why I am happy with Pro3.
My experience is very good with Reliance Pro3. Please always get a demo at the place of usage then buy the connection. Being mobile broadband, it is prone to signal drops and weak signals within the same house.
