Roku TVs routinely earn high marks in CNET's reviews for their ease of use, superb streaming options and, in one example, excellent image quality.

Unlike its streaming devices, however, Roku doesn't actually manufacture the TVs. Instead it partners with original equipment manufacturers (OEMs), brands including TCL, Sharp, Hisense, RCA, Hitachi, Insignia and, as of today, Magnavox. The licensing program has been quite successful. Roku TVs regularly appear on Amazon's best-sellers list and the company claims that in the first three quarters of 2017, one out of every five smart TVs sold in the US was a Roku TV.
