If you own an Insta360 X4, this lens cap is a no-brainer. It’s like giving your camera a bulletproof vest—simple, effective, and totally worth it.

Pros: The fit is *snug*—almost like it was molded for the X4. I’ve tossed my camera into backpacks, pockets, and even dropped it (oops), and the lenses stayed scratch-free. The silicone material feels premium, not flimsy, and those ventilation holes are a smart touch to prevent overheating.

Cons: It’s a dust magnet—expect to wipe your lenses every time you remove it. Also, fitting the camera into its case with the cap on? A bit of a puzzle. And yeah, it’s odd that this isn’t included with the X4 given its price tag.

Real-world use: I use mine daily. Slap it on when I’m not filming, and boom—no stress about lens scratches. Perfect for travel or just stashing the camera in a bag. For $6? Absolute steal.

Verdict: Skip knockoffs. This OEM cap is the real deal—durable, practical, and peace of mind in silicone form.
