Review on Optical Lens Dust and Fingerprint Cleaning Pen for Oculus Quest 2/Quest/Rift S/HTC Vive/Cosmos/Valve Index /PS4 VR Headset, Drone, Microsoft HoloLens, Cameras by Dan Weeman

I like the side with no brush to get lens marks. Although in places like the instructions say you can't go all the way to the edge. The brush is nice and soft but not long enough to reach the edge of the lens and I constantly feel like I'm scratching the lenses. Overall it would have been worth it if the price was under $5. They're just exploiting the fact that new people to VR like me want to find a way to solve the dirty lens problem.
