Let me start by saying this camera is a game-changer for capturing action shots. The 8K resolution is mind-blowing—whether I'm carving through mountain trails or cruising city streets, the footage looks like it's straight out of a professional sports documentary.

The invisible selfie stick effect? Pure magic. It genuinely feels like I've got a drone following me around, especially when I'm riding solo. No more awkward angles or missed moments—just epic, cinematic footage with zero effort.

Battery life has been solid for my day-long rides. I easily get through 3+ hours of recording, though I always pack a spare battery just in case. The waterproof feature came in clutch during an unexpected downpour—not a single hiccup in performance.

Editing does require some patience (and a beefy computer), but the Insta360 app makes reframing shots surprisingly intuitive. My favorite trick? Using the GPS data overlay to show my speed mid-corner—it adds such a cool element to ride videos.

The lens guards are my only gripe—they could use a more secure attachment system. After one particularly bumpy off-road session, I found myself double-checking they were still in place every few miles.

Despite this minor issue, the X4 has completely transformed how I document my rides. The stabilization is so good that even my roughest trails look buttery smooth in playback. This isn't just a camera—it's like having an entire film crew in your pocket.
