This seemed, at first, to be one of those "too good to be true" products to stay away from, but I'd been trying to find a way to eliminate the long distance fee from my phone bill ($20/mo.) without causing a lot of inconvenience, and this was one of the possible options. Can't remember where I'd first read about it online, but the link led me to a free 30 day trial offer that I felt safe checking out as it would only cost me the return shipping if I didn't want to keep it. Arrived within 2 days and was easy to set up; I even found a good 2.4 GHz cordless phone on sale to hook up to it - had to make sure it worked throughout my home. I got a phone number with my area code which shows up on Caller IDs, but without my name, which is ok.
Seems to work just fine, but the jury is still out, and until I'm certain of its reliability I'll keep the long distance service with the phone company. I've been using it occasionally for the past 3 months, and need to make sure it'll work with a new wireless router that I just picked up, but haven't yet installed.
My primary concern was that it kept causing my computer to reboot at least once whenever I first turned it on, but that was apparently resolved once I moved a few start-up programs into the delayed startup category provided by WinPatrol.
Yes, you do need to keep the PC on all the time if you plan on using it as a total phone alternative, and I think that that's what the developers had in mind, so you're not warned about the reboot issue. I intend to use it solely for long distance calls, and if I can continue to make it work, that will save me a lot of money in the future.
I am also concerned about a reported lack of customer service and that alone may be the deal-breaker. At this point, if I so choose, getting a refund would prove difficult, though certainly not impossible; I'll get my money's worth regardless, and I don't have to renew unless I want to.
While this might eventually become the incredible product it's hyped-up to be, approach it as you would a "beta" offering. Here are a few places to see the problems that others have encountered and endured with magicJack - you'll have to sort the bs from the truth yourself, but it's a good starting point:http://www.complaintsboard.com/bycompany/magicjack-a40340.htmlhttp://iripoff.com/872/MagicJack.com_-_False_Advertising.htmlhttp://magic-jack.pissedconsumer.com/
If you decide to pursue this, even if it's the 30 day trial, just make sure to use a major bank credit card, and definitely not a debit card!
Hope this was helpful...
