I have been using spectranet internet service from last 3 months in Pune and its really awesome. I have constantly monitored the internet speed and its always around 15-16 mbps. This is by far the best internet service I have had until now.
Sometimes there are issue with internet service but they are quickly resolved by their team and they provide great follow up on the issues reported. This is my personal experience with spectranet service, thought to share:)
