Walmart onn. 4K Pro Streaming Box Review: The $50 Sleeper Hit

Bottom line: Walmart’s onn. 4K Pro ($50) is the best-value streaming box right now — Google TV with Ethernet, USB-A, and Dolby Vision for the price of a basic stick. The 2GB of RAM shows its limits when multitasking, but nothing else offers this much connectivity at $50.

Overview

Walmart sells its own branded streaming devices under the “onn.” label. The 4K Pro Streaming Box is the premium model — a standalone box (not a stick) running Google TV, with Ethernet, USB-A, and a microSD card slot for expanded storage. At $50, it undercuts the Chromecast with Google TV and Roku Ultra while offering more ports than either.

Performance

Surprisingly strong for the price. Google TV’s interface is smooth, apps load quickly, and 4K Dolby Vision content plays without hesitation. The 2GB of RAM is adequate — the occasional app reload when multitasking, but nothing that disrupts day-to-day streaming. It uses the same Amlogic S905Y4 chip found in several budget Android TV boxes, and it’s well-optimized here.

What We Liked

• Ethernet port — wired connection on a $50 device is exceptional
• USB-A port — play local media or attach peripherals
• MicroSD slot — expand storage for more app installs
• Google TV — full content aggregation, Google Assistant, Chromecast built in
• Dolby Vision + Atmos — premium formats at a budget price
• No account required to browse — unlike Chromecast, can skip sign-in for basic use

What We Didn’t Like

• Only 2GB RAM — apps occasionally reload in the background
• 8GB storage — fills up with a handful of heavy apps
• Walmart brand stigma — people overlook it because of the label
• No backlit remote — hard to use in the dark
• Slower chip than Chromecast — Google TV Streamer is noticeably snappier

How It Compares

For $50 it embarrasses the Chromecast with Google TV, which lacks Ethernet and USB, and undercuts the Roku Ultra’s wired-box pitch by a wide margin. The trade-off is power: the Google TV Streamer is meaningfully faster with double the RAM, and the NVIDIA Shield TV Pro is in another league for Plex and upscaling. But on pure value, nothing beats the onn.

Verdict

The onn. 4K Pro is arguably the best value streaming box available right now. Ethernet + USB-A + Google TV + Dolby Vision for $50 is a combination no one else offers at this price. The hardware cuts are real — 2GB RAM and 8GB storage show their limits — but for casual streaming it punches well above its weight. Worth considering if you’re on a budget and want more than a stick.
