That's just your personal opinion and not that of the majority. Every time someone has a problem they automatically consider it "junk", when 90% of the time it's nothing more than operator error. Reception can be distorted by many things including motors running in appliances that are on the same circuit as the camera, as well as your neighbors having either wireless camera's to wireless routers for their home networks.
I realize that some will be pissed at me for my comments, but I've been an IT person for over 25 years, before most of you even knew what a computer was and have seen it all and then some. It's all about technology, and if you don't take the time to understand and learn about something before or even while you start using it, you're guaranteed to have issues, most of it being operator errors. It's not to say X10 doesn't have issues with some products, afterall, they are mass produced like automobiles and damn near everything else you buy. Now tell me that GM or any other larger corporation hasn't had major issues and recalls far worse than X10 has ever had...... you can't and be honest about it, period.
