Is the Fire TV 4-Series 43-inch worth it at $100?

At $100 at Mercari as of November 4, 2026, it is a strong deal for a basic 4K TV. It suits a bedroom or spare room; if you care about picture quality, spend more on a brighter set.

Do I need a Fire Stick with this TV?

No. Fire TV is built in, so Netflix, Prime Video, Disney+ and other apps run on the TV itself. You only need a stick if you want a newer or faster streaming interface.

How does it compare with the Fire TV Omni series?

The Omni line adds better brightness, hands-free Alexa on some models and improved picture. The 4-Series is the cheaper entry point and is fine for casual viewing.

Is 43 inches big enough for a living room?

It is best for bedrooms, kitchens and small rooms where you sit 5 to 8 feet away. For a main living room, most people prefer 50 inches or larger.

Does it support wall mounting?

Yes, it has standard VESA mounting points, so a typical 200 x 200 mm wall bracket works. The stand is included if you prefer a tabletop setup.

When is this TV cheapest?

Fire TV sets usually drop around Prime Day, Black Friday and Amazon device sales. The $100 Mercari price as of November 4, 2026 is already near the bottom of its recent range.

Our take on the Amazon Fire TV 43" 4-Series 4K UHD Smart TV

The Amazon Fire TV 4-Series is a budget 43-inch 4K LED TV with the Fire TV interface built in, so you get Prime Video, Netflix and Disney+ without a streaming stick. It has four HDMI ports, HDR support, a 60 Hz panel and Alexa voice control through the remote. The best new price is $100 at Mercari as of November 4, 2026, and three stores list it new. That $100 is at the low end for this set, which normally sells for roughly $150 to $250 new depending on the sale.
