I bought a magic jack the other day at my local radio shack store. I took it home and installed it set everything up as per set up screens asked me to you know name address and other info. i made a few calls successfully with it and it worked fine. Then i tried it a few hours later and i was not able to call anyone it kept cutting me off when i was trying to dial a number. or when i did get through i had to almost scream in to the phone to be heard. I even tried calling my friend on his cell number and he was not able to hear me. i had to go to my other line in my apt to call him back to tell him that it was me that tried to call him I told him what I was useing to call him on and he said he bout one of those and it did not work for him. And my friend knows computers and eletronics for he has 4 degrees in it and is a computer tech person so hen he said he had problems. I know that this item was a piece of SHI- So i took it back and got a refund the man at the store asked me for the reason i was returning it i told him it was garbage I suggest people that have been ripped off by this product contact the so called inventor MR Daniel Borislow at his home address his home address is MR Daniel Borislow 1045 south ocean blv palm beach floridia 33480 I think everyone that has been ripped off by him and his company should flood his personal mail box with complaint letters and to file a report with the flordia Public utility commission and the FL attorney generals office and the fcc. If i get more info on MR BORISLOW I shall post it here I am trying to get his private email address and his private phone number and when I do I shall Post it here !
