I have had to return 3 of the Ultra's to Walmart because they failed in less than 30 days. The last one I took back of the is weekend 7/17/22. Walmart is a seller and must comply with 15 USC 2304 et.seq. and refused to warranty. So I contacted Roku. The company was completely non-reponsive to this issue. My wife is disabled and watches TV most of the day so I purchased another Roku (a small one) to get her Tv. When you follow the instructions provided by Roku to return your product the are also NON RESPONSIVE. You are required to obtain a return authorization which I have been waiting for and no response. Given, when it works it works, but the product is defective in soooo many ways. The return of 3 in since March of this year is unconscionable, dis respective and insulting. Had I know these were such junk I would NEVER have purchased the first one.
I still own the Roku Express+ 3910X (also bought from Walmart), after two years and it has not failed as of yet. It is possible that you either bought units with internal failures, or the units were once returned by previous buyers.
I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
