the problem with message boards is that you never know when the people doing the flaming are the companies competitors. to be fair, you also never know which of those doing the praising may work for the said named company. so take everything you read on forums and add some of your common sense to it and you can pretty much figure it out.
all that being said, i have some input on the magicjack device for you...
i ordered it under a free trial. i figured if they were gonna ship it to me and let me use it before paying for it, it couldn't be all bad.
I WAS RIGHT.
this little device is wonderful to say the least.
it does NOT install a bunch of..or ANY that i can tell or see, spyware or adware. i never had popups before using it and i have never had any since using it.
you can tell this is true by reading all of the above posts. on every forum, there is someone there to say ADWARE.....SPYWARE...but if you read on and find the reviews by real users, they will tell you that they too have HEARD of people having adware issues, but they themselves have not noticed any. nor have i.
i have never had it crash a computer, or affect it in any way aside from the magic jack box popping up on the screen when the phone rings or the handset gets lifted to use the phone.
the ads in the mj box that the real users do speak of are in no way intrusive or annoying. they are just a little section on the left side of your mj box on the screen...and since you will always have this box minimized, except for when it pops up as mentioned before, you will never see these ads...or so called ads. they are more user tips than anything.
let me add at this point that while the box does go from the tray to on the screen when the phone rings or you lift the set to use it, you CAN minimize it right back to the tray...EVEN WHILE THE PHONE IS STILL IN USE.
I had never had any of the the problems people mentioned here regarding clarity or broken sentences.....AT FIRST. no, this is not going where you think it is...sorry mj flamers.

then, about a week ago, the phone started breaking up on me, no static, but lost words and incomplete sentences. I unplugge it from the pc and restarted it to no improvement. i rebooted the puter...no improvement. NOPE, Still not going where you think it is...

. so then i check on my interent connection speed. i am on laptop running wireless between router. BINGO, I found my problem. my wireless was only connecting at 36 or 38 mbps. WELL, i grabbed my cat5 cable and plugged it into my laptop and turned the wireless off. problem was gone, simple as that. now, i have since moved my router and returned to running wireless again, again with no issues, but it seems pretty imperative that if you use a wirelss connection, it needs to be connected with at least 48mbps, and mine is now staying connected at 54mbps.
so if you do plan to use mj, make sure you plug it into a computer that is hardwired to your router, or else make certain that you have a decently fast wireless connection to it. all that being said, i am pretty sure it would prolly suck on a laptop out in the field, using either a cellular connection or wi-fi with weak signal.
one cool thing i like about it is the call log. this thing has a call log on mine dating back to the first call i made on 4/15/2008 all the way to the last call i made today. something like 196 calls total so far. inot sure how high this number will go, may only hold 200, maybe 500, maybe 1000...who knows, but i do know this....if i take the mj out of my puter and put it into another one, my same call log still shows in the mj box on screen...all 196 calls.
another neat trick i like is to unplug it from my puter and take it with me when i go to a friends or to travel. i can plug it into their puter, or my laptop, add the phone and make calls to people, WHO ASSUME FROM THEIR CALLER ID, that i am calling from home, when i am in fact, NOT AT HOME.
i use my mj for business believe it or not. telemarketing to be exact. i know, i know, i suck, telemarketers are bad, blah blah. none of my customers have ever had any issues hearing me or vice versa. and, if it continues to work as it is, i plan to add another mj phone....and i even plan on trying to run the second phone on the same puter, different usb plug. not sure if this will be possible since the two may try to use same popup box or some other issue, but i'm prolly gonna give it a go.
it also makes a great second line to dedicate to a fax machine. provided you do have a good internet connection and connection to your router. This seems to be the most important factor, and i would be willing to bet that most all the people who do have issues with it are experiencing some sort of packet loss from a poor or too slow connection.
FYI...i am fiber optic broadband internet through verizon fios. when i take the mj with me to friends, there i use it on cable modem broadband. works fine on both of these. i can not speak personally for dsl or any other.
and hey, lets face it, for the price, how can you go wrong....
i read here that someone suggested not to pay for extra years if service in advance. i dunno what to say about this subject or how to advise. i personally wish i would have bought into the extra years of service for discounted price since mine works so good. in fact, it works SO GOOD, that i am sure they will raise the price on me in the coming years. this is why i wish i had bought the extra bonus. for you, i dunno. hard to say until you get it and try it, unless you are really sure you have a good internet connection and decent pc. cuz it does seem that some people experience static and broken sentences when their connection isn't up to par.
my advice to you is get it and try it. if you do it now, they may still have the free offer on their website. i haven't looked again since i got it. if they do, you really have nothing to lose. i love mine and have suggested it to friends as well. of these friends, only two have gotten them, and both of them love them as well.
i hope i have been helpful.
