Walmart made quite a splash in the budget TV business a few years ago when it introduced its home Onn line, and continues to undercut its rivals even as it tries to offer the best deals on Cyber Monday.

Right now, Walmart is offering a 70-inch 4K UHD Onn Roku Smart TV for an incredible $448. That's the lowest price we've seen this weekend for a TV of this size and resolution. And this isn't even marked down for the Cyber Monday TV deal - this is the regular list price of the TV.

In our review of the Onn 50-inch Roku Smart TV, we liked the small but very versatile voice-controlled remote, which is a customized version of the usual remote that comes with Roku set-top boxes and streaming sticks. However, we thought Onn's colors could be a bit brighter and the sound a bit louder. Perhaps you will want to check out one of the best inexpensive soundbars.

Despite our concerns, Onn's 70-inch Roku 4K TV is getting rave reviews on Walmart's site. Aside from the physical compromises of the set itself, there's no denying that the Roku interface is great; the Roku interface is probably the easiest to use of any smart TV interface and offers a wide variety of streaming services.
