Is the SJCAM C100 Plus worth it?

Yes if you want a tiny, cheap camera for helmet or body mounting and can live without a screen. If you need strong low-light video or a viewfinder, spend more on a larger action camera.

Does it really shoot 4K?

It records 4K at 30 fps, plus 2K, 1080p at 60 fps and 720p at 120 fps. The small 1/3-inch sensor means 4K looks best in good light.

Is it waterproof without a case?

No. The 30 m rating applies with the included waterproof case. Do not take the bare camera underwater.

How long does the battery last?

About 87 minutes at 4K, 106 minutes at 2K and 127 minutes at 1080p. Carry a spare battery for long shoots.

The listing confirms a rechargeable battery. Check the full bundle for the waterproof case and mounts before buying, since kits vary by seller.
