The Ultra remote is great BUT it is useless in the dark since it doesn’t have lit up buttons. It needs that feature!
@Baruch A Roku Voice Remote Pro (2nd Edition) has backlit buttons. Be aware it has no headphone jack.
Can always install the Roku mobile app on your phone and use as a remote as well. (plenty of light from the cell phone/tablet). https://www.roku.com/mobile-app
The backlit Voice Remote v2 mentioned by @HDMIGuy can be found on the Roku accessories page. https://www.roku.com/products/accessories
