Brian, thank you for your advice. I have marked it as "Helpful"
Unfortunately when I called customer service (after 30 minutes of waiting on hold before getting to talk to somebody) they think that it might be a defective RE549 unit. I was also having problems with some of the regular X10 stuff because of the wiring in my house (worked on some outlets, but not any near my entertainment center where I needed them, I am not willing to invest more time into figuring it out... it just wasn't that important to me). They were unable to tell me how much of a credit I would get for a partial return of the "package deal" I purchased would be. I asked for clarification since the remote and extender were $X price and the package I got was $Y price being the package $X plus extra items, why not give me $Y - $X (- free shipping code discount would even be acceptable). The person on the other end just snapped back at me that they were unable to tell me how much of a refund I would get until it was processed as a partial return. I explained that I did not find that acceptable and would like an RMA for the entire purchase and the person said "Ok, you will receive it in your email, goodbye *click*"...
This truly is a shame since if the product had worked better OR the customer service was even halfway acceptable then I know a few people that were waiting to hear about my experience in hopes of it not being "too good to be true". The remote was acceptable, maybe even exceptional for the price, the repeater may have been replaceable and I may have been a happy X10 customer for years to come...
