Let me try to clarify. I received an IR/RF remote from etronics back in April. The IR portion of the remote worked perfectly but the RF did not comminucate with the IRF6. I sent the remote back to Mitch and they quickly changed the Rf frequency to work with the IRF6.
You can read my first review of the remote under the "$650 ++ Worth it? let the debate begin!" thread.

I can only say good things about RTI, Mithch, and etronics.

Let me know if you have any other questions.
