I have used idea net setter.Trust me, it really sucks. We know idea as one of the good service provider in Maharashtra, but this product is a disaster. Whenever i connect this to my PC to browse any site, I rarely get good speed.
Web pages takes a long time to open, many times i go to sleep while waiting for a web page to open. Customer care service is of no use they never responds to your problems and calling them is complete waste of time. Instead, i would suggest for to take GPRS connection.
I would suggest not to buy idea net setter. In the end " kya bakwas idea hai sirji".
