rip off, or does it work from AC ?

Remember Google is your friend. LOL

Here is a forum on it. http://www.magicjacksupport.com/ Hope this is helpful. I have never talked to anyone that had it BTW.

Its not a con Magic Jack does work.
Ive had mixed luck in San Pedro
I couldn't get it working using internet through BTL (What a suprise!!)I got dial tone but couldn't make calls
However, with our new Satellite internet in San Pedro it works really well

I have one in the states and it works great, I was told as long as you have high speed internet it will work in Belize also same price.
