I've used virtually all Smarthome products in my house and have been very pleased. I was concerned about reliability as my wife would be very upset if she started using things and it didn't work properly given the investment we made (about $5k). They've worked great. And in the limited occasions where I've had problems (either a switch was bad, or in fact for some items, I've damaged them on installation), Smarthome took it back and replaced it no questions asked. The biggest inconvenience has been going to the Mailboxes Etc. to ship it back. They even shipped the replacements with no shipping costs to compensate me for the cost of returning the replacements on my nickle. First rate customer service. That's very important to me, aside from the fact that their products are outstanding. Just MHO.
