I am using this Tata photon+ for past 10 months and quite happy with it’s performance. I bought it from shimla, HP and consistently getting 800 kbps to 2 mbps speed, apart from shimla I have used it in Kolkata also and getting almost the same speed, on very rare occasions speed dips below 200 kbps. Customer service is also very helpful and responded promptly whenever I have any query, problem although I never really have any problem till now.
Even when I am traveling by train I am getting enough signal most of the time to check e-mails etc. during downloading from torrent it normally takes 7-8 hours but sometimes as low as 2-3 hours, live streaming of youtube videos is also good but sometimes it do get stuck. Overall I can say that this product fulfilled my expectations.
