The Harmony Pro doesn't have hard number buttons. Isn't that alone a reason not to want to use it? Much less give it to a customer? Wouldn't a MX 450 be better? Its been a few years but I was installing a MX 600 on every job that wasn't c4. It could do everything I needed and it was $450 programmed. Never even gave the customer a price for the remote it was just part of the system.
