I've also purchased the Rii RT-MWK13 and it's really good. It's well built and works perfectly.
I've replaced 6 remote controls with just this one, now I control: TV, HT, cable tv, room fan, room lights and HTPC.
.
It learns very easily, and during learning process, my suggestion is to put the other remote control very close to it, touching infrared's.
Pros:
Infrared: well built, control up to 8 different IR devices, has almost all necessary buttons. learns quickly. controls from a long distance
RF Keyboard: well built, mouse works fine,
general: I've disassembled and confirmed the pcb is well made, the buttons are not that type of plastic with carbon contact, all button are like a tact switch, so it should not wear out so fast after some time.
Cons:
Infrared: None
RF Keyboard:
-the antenna is pcb made on the left of the keyboard, so depending the way you hold it, it reduces the signal strength, and starting from 4m more or less, it can stop communicating, so it's needed to hold in a different way on the left side of the remote control.
-It doesn't have the F1 to F11 buttons.
-The keyboard is not on the standard format, so for example to increase the volume on XBMC it's needed to press Fn and +, instead of just using the key "+=", not a big problem for me as I can control the volume of the home theater via infrared.
-It's tricky to calibrate the mouse, don't lose the manual, otherwise you'll never remember how to do it.
- Doesn't have back light. (This one I really miss)
General feedback: It worth buying and I do recommend purchasing this awesome product. As you can see on below picture, I used to have all those remote controls on the left on my sofa, now I just have the remote on the right.
