After that, I used the app to place my receiver under the right TV HDMI input, and then dragged the rest of my devices under my receiver's HDMI connections. The entire setup process took around 10 minutes, but it was relatively painless. After connecting the Harmony Express to my Alexa account, I held down the voice button on the remote, said "Turn on Xbox," and my TV and receiver automatically switched to their appropriate inputs. Saying "Play Hulu" switched everything over to my Apple TV 4K and automatically launched the streaming service app.
At first, the Harmony Express felt like everything I'd ever wanted in a modern universal remote, my entire entertainment system at my beck and call. But it wasn't too long before I noticed limitations: It can only launch apps, it can't play a specific movie or TV show. And it's not compatible with any of the Apple TV or Roku's voice commands, which means it can't take advantage of either boxes' voice search. Basically, you'll still need to keep your Apple and Roku remotes around. Logitech says it's working on getting deeper integration with those platforms, but it's unclear when, or if, that will happen.
As a standard remote, the Harmony Express feels comfortable to hold, with a rounded bottom half and smooth plastic finish. It's thicker and chunkier than the Apple TV remote, which means you're less likely to lose it in the couch, but it's also slimmer than Roku's bulbous controller. A circular ring on the top serves as your directional pad, while the center holds your standard "OK" button. Hold that down, and blue LEDs light up, telling you it's ready for voice commands.
The remote has only nine other buttons -- a breath of fresh air when compared to Logitech's previous controllers. On top of the expected volume and playback controls, there are back, home and menu buttons. A few also do double duty, a long press on the mute button turns off everything, while holding down Menu opens up options on some devices. There's a speaker on the back for Alexa's responses, which can get surprisingly loud (you control its volume through the app). Finally, a micro-USB port on the bottom lets you recharge the remote.
The Harmony Express is a serviceable remote for navigating the Apple TV's menus, my LG TV's options, or the Xbox One X's interface. But since it's relying on IR to control everything, there's a slight delay between hitting a button on the remote and the on-screen response. Apple and Roku's remotes are wirelessly connected to their set-top boxes directly, so they'll always be faster. Simply put, the main reason you'd want a Harmony Express is for simple voice controls.
