Great product if you want what it offers, which is 1 voip and 1 PSTN "line" with the ability to wander around your house while calling. I had to use the browser set-up. It shows the unit as being a C450IP, strange. But the setup is easy and it was working on both fixed and Voip calls within 2 hours of opening the box in spite of my SIP provider not being in the menus for handset based setup. The DECT range is at least 50 metres into the garden, much better than wifi here. I am using a Netgear DG834G ADSL modem router (without any forwarded ports) on a 4Mb connection. and voip quality is better than with my Grandstream GXP2000.
