The Magic Jack plugs into a USB port. I have enjoyed using my Magic Jack for over a year but last night the unit broke away from the USB plug and fell to the floor. The USB plug appears to have had 4 points that were soldered (not well) to 4 points inside the unit and that's all that held the 2 parts together. The Magic Jack is too heavy for the plug. I always noted that the weight made the unit hang down a bit. They won't replace it since it broke on my end. I am not willing to pay another $50 or so to replace it. SO..IS THAT HOW THEY ARE ADDING TO THE BOTTOM LINE AND SELLING SERVICE SO CHEAPLY? By selling such poorly made units that they know you will have to replace them>

I used Magic jack (#1) on my desk top happily for a year, and period expired but I kept it connected, and used it once in a way. It showed a message it will expired shortly, please renew. I did not renew, few days later, suddenly it said upgrading and changed / screwed up my entire window xp pro. Changes to the system made by Magic Jack did not allow to use restore point. Computer started freezing, not working properly. After few restart it worked ok but all restore point were useless. I had another Magic Jack (#2) which is brand new, I connected and it did not work at all on that desk top computer, but it worked on laptop fine. Contacted tech but they could not make it work, their knowledge was limited it did not work at all on my desk top, and on lap top it worked fine, without any effort.
So I formatted my desk top and re-installed xp pro but still Magic Jack (#2) will not work, I contacted tech they could not make it work. It appears that MJ is copying xp serial key or some file (How Microsoft recognizes your system) and not allowing me to even use NEW MJ (#2) on that desk top computer. When service expires they should stop allowing use and not screw up OS. I am going to look for class action attorney to look into this. FCC is useless, they don't do any thing. If anybody has such experience please report here for attorney to look seriously.

I have the magic jack now and so does my dad. His phone works pretty well but mine is crap! 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.

I bought Magic Jack on a Thursday night and we were unhooking it and trying to reboot it by Friday night. Tried it for a few more days. Today is Sunday and it still won't complete calls, cuts off numbers, and puts people on hold for no reason. This thing has a mind of its own. Taking it back to Radio Shack as soon as they open. This is ridiculous. I guess if it sounds too good to be true it really is. This product is not recommended to anyone as most of the time the calls do not go through. My mom tried to call me for 2 hours Saturday night and she said the number was busy the entire time when no one here was on the phone.

BEWARE OF FRAUD. THIS THING NEVER WORKED, I DID THE LIVE CHAT WITH THEIR CUSTOMER SERVICE AT LEAST 7 TIMES, AND EACH TIME NOTHING HAPPENED IT DROPPED CALLS WHILE I WAS TALKING WOULD GO OFF THE SCREEN THEN COME BACK THE SOUND QUALITY WAS TERRIBLE. SOMETIMES I COULD NOT HEAR THE PERSON ON THE OTHER END, OR THEY COULD NOT HEAR ME IT WAS A SHITTY EXPERIANCE. NOW I HEAR ON THE NEWS THEY HAVE OVER ONE THOUSAND COMPLAINTS AT THE BBC. PLEASE GO THERE AND COMPLAIN TOO. THE HOME PAGE SHOWS THE INVENTOR, AND HIS DAUGHTER, HUM I WONDER IF SHE KNOWS HER DAD IS A SHISTER
