Okay so you put it in your own home. Great. Have you installed it for any paying customers? That is the question. I have put a lot of things in my own home that worked great for me, but I wouldn't sell them.
You had a bad ELan install in your previous home. It happens. There are hundreds if not thousands of ELan installs that were done well and the homeowners love that. Crestron has thousands of installs that are loved by the end users. They have some bad ones too.
The Elan system in my house is fantastic. It works well and is easy to use. Anyone who comes over can make it do anything they want. That is not the point. How many of your paying customers are happy with this system, what kind of 'snags' did you hit? I really want to know these things, I'm not just trying to be a d%^k. I have a meeting set up with my local rep after EHX to discuss this product. I would really like to know about some real world experiences.
