It works and it is easy to set up (almost plug and play), but sound quality is bad on intl calls and sometimes impossible to connect to cell phones overseas. Local calls quality is acceptable, but for local calls it is cheaper my local phone provider.It DOES NOT work well on DSL lines, as upload speeds are always in the low 100's... if you have an upload speed of less than 250 and download of less than 500, you will have a very bad line with lot of noise.Still a better alternative (if your main issue is to reduce your bill on Intl calls) is to buy calling cards you are familiar with. Not as convenient but you can connect when you want and at a low price.Customer service: It is really hard to get to a live rep. Give it a try before you buy this service and see if you can get to a Technical support rep at the firts try w/o listening to "sorry our reps are busy" 1-866-243-4357.Check several available discussion forums before making your decision. This is a great new technology, but quality still bad and non acceptable.They processed my return properly and got my money refunded, no complains on that aspect
