Remotes, am I right? Yeah, I know. What are you going to do with them?
One option is to toss them all out and replace them with the Logitech Harmony Smart Control. You can then use one interface to manage your Sonos sound system and your Amazon Fire TV Stick. Logitech Harmony will also let you control your Nest Protect thermostat or some Philips Hue lights, but this particular remote doesn't come with the buttons you need. You would have to resort to the Android app for those.
But first, you probably want to actually buy the remote. Fortunately you can snag one on Amazon for only $75. That's a significant drop from the usual price of $130. The deal ends in just under ten hours.
