Material is around -2 on the reviewer's scale, relatively clean, not excessively oily, with a mild chemical odor up close. The source finds similarities to COOLP 性处理女仆 Soft in material and five rotating ridges, but shared manufacturing is unconfirmed.

Channel and assessment

Fins replace the comparison model's bumps. They are broad and thin at the front, progressively smaller toward the rear and irregularly arranged. Front feedback is distinct, varied and comfortable; the rear is less defined. The body feels soft yet reasonably shape-stable. The reviewer prefers these fins to the compared granular structure, while noting thin local walls and operating noise. Shape stability does not establish tested durability.

The varied front is the main strength and local thinness the limitation. Final recommendation: 4 stars.
