What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Roku Ultra (2024)
Three whitelisted hands-on reviews (TechRadar, PCWorld, Tom's Guide) survived verification, all covering the exact 2024 Roku Ultra. All three praise its speed versus Roku's cheaper streaming sticks/dongles and the backlit, USB-C rechargeable Voice Remote Pro, plus Roku's deep catalog of free content. All three flag intrusive and growing home-screen banner ads, and PCWorld and Tom's Guide stress it is barely an upgrade over older Ultras. Note: full Dolby Vision/HDR10+/Atmos support is enumerated in full only by TechRadar; PCWorld cites only Dolby Atmos and Tom's Guide only Dolby Vision. (3 sourced reviews, 3 lab-tested.)
Praised: Speedy performance, clearly faster than Roku's cheaper streaming sticks/dongles; Backlit, rechargeable (USB-C) Voice Remote Pro; Excellent library of free ad-supported movies, shows and channels.
Flagged: Intrusive and growing banner ads on the home screen; Barely an upgrade over older Roku Ultra models; Expensive relative to other Roku streamers / at the high end of the category.
