Seams at the very least it has problem repeating any extended codes. Although I had a customer that could not get it to do anything. I hate to knock any product (they all have their place) but this one seams like a problem, I a least a dozen e-mails from customers who finally got fed up with the HCA and sent it back, to their dealer. The price is good on it, but a good repeater is supposed to make your system more reliable, not less. If you want a good one go with ACT,
[Link: act-solutions.com] they make them for industrial applications and they do the job.
