Wasn't sure about the whole sphere thing at first, but the inner texture really does grip in a way that feels way more intense than a plain sleeve. Cleaning takes a bit of effort because of the ridges, but that's honestly the only tradeoff.

The textured spheres inside really do most of the work here, way more intense than the smooth sleeves I've tried before. Cleaning takes a bit of effort with all the ridges, but honestly it's worth it.

Didn't expect the inner sleeve to feel this intense honestly, those textured spheres hit way deeper than I figured. Cleanup's simple too, which matters more to me than I thought it would.
