When I bought this product I thought the set up was fairly easy. As it turned out, that was true, but ONLY when I was connecting to MY desktop from MY laptop on a shared router in MY home. In other words, up to 25-30 feet away from one another.
Connecting via the internet was an entirely different story. A complete NIGHTMARE, and the kicker is their program is designed primarily for use over the internet. You practically need to have enough knowledge/skills to work for them (in tech support) to get it to work. You'd think a company selling PC to PC software would be able to connect with their own customers that way, but you'd be wrong.
Their support and attitude towards their customers is terrible, to the extent that they censor comments on their forum, removed complaint posts altogether, and then blocked access to their entire website when I started asking about a refund.
Too bad they didn't put half as much effort into helping me as they did into silencing me. They couldn't get their program to link my IP address to other computer IP addresses but they damn sure blocked my IP address from accessing their site in a hurry.
I'd strongly advise doing extensive research on their products before buying, and make sure you have an excellent understanding about firewalls, IP addresses, routers, virus protection software, etc. You're gonna need it.
