Will it work with my TV?

It is a universal infrared remote meant for most major TV brands, and you match it to your set by entering a brand code. Check the code list for your brand before buying, since less common brands may not be covered.

Does it need batteries?

Yes. It runs on standard AAA batteries, which are usually not included, so budget for a pair.

Can I use it in the dark?

Not easily. The buttons are not backlit, so you will be pressing by feel or turning on a light.

Does it control a soundbar or streaming box?

It is built as a TV remote. It may handle basic TV volume and input functions, but it is not a multi-device remote for a soundbar, game console or streaming stick.

The remote itself, and typically a code list or quick-start guide. Batteries are generally sold separately.

It is a low price for a universal remote, and only one store lists it new. There is little room to save further, so buy when you need it rather than waiting for a drop.
