I'm generally not a fan of Fanvil products - however, I gave the W611W a try as VoIPon offered it at a reduced price.
Whilst I agree that the phone is value for money and looks nice, it is let down by the usual Fanvil poor user interface on the phone and web GUI for set up.
I find the audio of poorer quality than the Grandstream range of WiFi phones and there is a constant low level hiss that once you notice, you can't stop noticing!
In the end, you usual get what you pay for and this phone is no exception.
Would I recommend it at this price point? Yes. Would I buy another one? No.
