I Got my DEN boomband broadband connection 10 days back. Installation was done in a day. I got the 10 mbps plan and untill now the connection is working just fine. Speed is exactly 10 mbps with good reliability. Download speeds is over 1mbps. Yes, the connection is lost sometimes but such problem lasts few seconds.
However, I WANT TO WARN that maybe in my case the speed is great because DENs main cable is located just outside my home. It might be offering greater reliability as against other reviews on the website
