For anyone who is wondering, the Sideclick universal remote attachment fits the new Alexa Voice Remote perfectly. While the main purpose of buying the Sideclick for many people is to add power and volume buttons to your Fire TV remote, if those added buttons on the new Alexa Voice Remote still aren’t enough, you can still use a Sideclick to expand its capabilities. Even though the first three buttons on the Sideclick are meant to be used for power and volume controls, like all the buttons on the Sideclick, they can be programmed to do anything you want. So if you’re using the new Fire TV remote’s built-in power and volume buttons for your TV, you can use the Sideclick buttons to control your soundbar, AV receiver, or anything else. See my review of the Sideclick for more information.
