I decided to try 1 last time to get the 15-1994 to learn the power on/off code for my Technics receiver, and I'll be darned - it did, and it did it to the power button on the 15-1994 so it'll be easy to remember where it is.
The remote now controls all the everyday functions I want it to. I'm thinking of getting a 2nd one to control my main system. I was going to get the Sony RM-AV2100 but who needs to spend $129-$179 when you can get a great remote for under $30.
