Majic Jack Informative - Before You Buy Get Informed
Don't trust any one reviewer on any product. Companies often have their shills place good reviews on consumer sites to bolster sales of their products. Check it out for yourself. Do a WEB search. It only takes a few minutes and can save you a lot of frustration in the long run. There are a lot of sites where VoIP services and equipment get reviewed by ACTUAL users. One review doesn't make for a good product and should prompt you to act. Magic Jack has both good and bad reviews in the marketplace and you should be aware of the pros and cons going in to your purchase.
It may be just what you are looking for, but then again it may not be the panacea it is touted to be.
