and I customized some other buttons as well.

Button mapping IR to IR works great.

It took perhaps 20 minutes to get things set up exactly the way my family expects them to work, and probably 10 of those minutes were finding other remotes from which to "learn" odd buttons.

I took 1 star off for not having a Sling hot key colored button in the same row as Netflix, etc and for the EXTREMELY overcrowded and SMALL key buttons

I checked a few other buttons and they all worked like a charm

I did was use the "copy" function (see manual) and now both buttons have the "instant replay" capability

You have to move the functions to the correct buttons yourself

Easy to set up, pre-programmed for Roku and similar boxes, and handy buttons to launch popular streaming services like Netflix and Amazon Video

This puppy has a nice heft and the buttons feel smooth and work the first time.
