I like that it is easy to set up, works well for my needs (business calls) & has been reliable so far! The only thing i dislike about this service compared to others out there in terms of price/features etc - its not as user friendly when making international calls from within Australia but otherwise no issues at all really!! If you are looking for an affordable way to make cheap overseas / inter-state callings then look into using optuloop live instead of buying another separate device just because they don't have unlimited calling plans here in Oz.
