Almost no sound, no need to worry about sound insulation at night. Very private experience.

Cleaning and maintenance are a bit more troublesome than imagined, but worth it for hygiene and durability.

The interior is relatively tight, suitable for users seeking strong confinement and quick release. Very stimulating.

The material is genuine TPE, very skin-friendly and soft, no rubbery smell. A big plus.

Used frequently, no tearing or obvious deformation after two months. The quality justifies the price.
