The original headline recommendation and experience score were 2 stars. This review concerned the transparent hardened edition, not the regular pink version. The author speculated that the latter might be milder but did not test it here.

The sample included one lubricant sachet; accessories may vary by batch. The compact body had rounded contours but felt very firm. The author compared it with R20一代 and found little elastic response under pressure. This was a feel assessment, not standardized hardness measurement.

Instead of conventional grooves, the interior mainly used large firm contact points: 2 adjacent at the entrance and another 3 distributed inside. A winding route increased contact locations. In use, however, the reviewer could not distinguish the sections clearly; large firm bumps dominated throughout.

The opening was very small and difficult to enter. Even substantial lubrication did not remove the hard-object sensation. The author reached the base at roughly 2/3 of their own contact range, finding the channel too short. No centimeter length was supplied. Firmness and limited stretch left little scope to gain usable length by extending it. A transparent base area made internal contact visible, without a separately verified function.

Intensity and tightness were very high, sometimes painful. Greater force should not be used to overcome opening or end resistance. The author considered limited resilience a durability drawback, without long-term testing. A short channel could help cleaning, but firm material, large bumps and several bends complicated it. Inside-out cleaning was not established.

Ratings: experience 2 stars; durability 3; cleaning 3; intensity 5; tightness 5; softness 1. Strengths were strong bumps and close contact. Limitations were excessive firmness, pain, the small opening, short channel and limited scope to extend usable length elastically.
