Although I am using it for a year but I would say it is not good enough. I got You Broadband installed last year and the every first month was pathetic. I almost had to call every alternate day to complain for not getting connection.
After a month, they installed new cable, and since then atleast the connection is alright and is working with some glitches.
I personally have noticed the speed is not up to the mark. I have a 2 mbps plan but even my videos sometimes buffer inspite of having a low resolution.
I would suggest to get a high speed plan if you go for you or its better to opt for some other Internet provider.
