What is the opinion of Reddit about the
iPazzPort Mini Wireless Keyboard with Touchpad for PC/Android TV Box/PS3 and HTPC, 2.4 Ghz, Black?

I’m glad to see someone else using a Raspberry Pi! I grabbed the iPazzport off Amazon and plugged it into the Pi, and this works for me.

I know it’s not a fix for your issue, but it’s a $15 solution if the remote you have doesn’t work with it.
