I just got one. They will give you a 15 day trial. Seems to work great and they are offering this deal to win people from Bell like myself. We added an unlimited long distance to the package and since I am a bell customer they gave me all the features I had with Bell like call display and answering service. The higher the Rogers signal you pick up the higher bandwidth you get. At my place the signal does fluctuate and so does my bandwidth but then it does that with most ISP's. The $50 dollar package only gets you about 3.5 GB per month and the cost goes up incramentally from there. I will likely use more and pay more but will still be cheaper than what I have now. I am a home office user and the guy on the phone asked some honest questions about our useage and was honest to say if you down load movies or are into gaming this may not be for you.
Its neat the way it uses a cell technology but emulates a home phone ie gives you a dialtone from the phone you plug into it.
