I need a small, discrete USB IR receiver for my R.Pi2 running Kodi in my lounge. Is something like this the kind of thing I need? It looks like it receives IR, sends it via USB to the R.Pi, and also re-sends it via IR as a repeater. Seems too cheap...

My son loves to grab this in one I current have in the TV cabinet. I use a Harmony remote so just need the receiver.
