We use it. Have had it for two years. No longer have a landline. Down side for us, need to leave computer on all the time. We have a Yuma #. When we go home ( snowbirds) we use a pay as you go cell. I give my cell number to my friends. If they phone me on my cell I just say let me call you back ( to avoid using my minutes) on my magic jack. We like it no long distance charges ever. Just paid $59 for 5 years of service.
