For all of us livining in Tijuana in need of a (619) number this is absolutly the best option. There is only one down side that i can see and that is your computer cannot receive calls while it is sleeping. Thankfully it comes with voice mail and notification via Email. Telnor which is the company I use for internet service blocks my Skype service. But they can't block Magicjack. And how can you beat the price at $20 a year.
