I have certainly gotten my money's worth, making about 500-1000 minutes of calls per month. Hopefully it will just keep on working because I don't intend to buy a telo or another ooma product, since they now charge monthly fees. To me, that violates the vision the company originally made to us early adopters: phone service that you buy once and own for life, like a product - "be your own phone company," they said. Probably if I was never part of the first wave, I would be able to look at the current ooma product line in a different light, but as it is, the new ooma looks just like every other telephone service now. All innovation is gone. I don't think ooma should be allowed to say "Free Home Phone Service" on their website and in their marketing anymore.
I'm waiting to see what Google Voice does with Gizmo5 - or I'll just use my cell phone, which I have to pay for anyway.
