I have the magic jack now and so does my dad. His phone works pretty well but mine is ***!
I have it hooked up to my laptop on wireless. Whenever I pick up the phone, it is choppy and breaks up worse than a cell phone. In order to make it sound half-way decent, I have to hook directly to my modem which does nothing for me because I have a router for a reason.
Now I have to get a real home phone for service because this one is very crappy! Unless you plan on using directly with the modem, I don't recommend it.
