MRL 恶魔MERU（杯子版） review

Images were selected by position and quality; individual human review is pending.

This text passed automated basic checks only; it has not undergone model or human review.

The source recommends 2 stars. The sample weighs 1064 g, measures 23 cm overall, with a 13 cm main channel. The secondary measures 6 cm, but its end is difficult to access and the reviewer's effective range is much shorter.

Silicone is identified without formulation testing. Personal feel is about +0.4, classified at +1 because stretch is limited; neither is standardized hardness. Exterior details look more natural than the reviewer's earlier related sample, with visible mold seams, not a rule for every silicone finish.

Both entrances are open circles. The reviewer suspects reduced pulling stress without crack testing or tear resistance guarantees. The main channel is wide; numerous small features are minor relative to its space and make little contact. Hand compression does not easily tighten it, air expulsion is nearly ineffective and air movement remains noticeable.

The secondary is short, simple and offset. Its 6 cm does not establish fully usable length. Alignment and support are demanding, without a separate numerical score.

A heavy upper body and lighter lower section rely on an unsupported waist. The forward opening and loose channel give little positioning support. It tilts in the hand and wobbles during movement, requiring effort to stabilize. Detailed shaping does not ensure practical handling.

Tackiness and a dry-feeling contact are more obvious than the limited softness benefit. The reviewer uses a substantial powder layer for surface feel, altering dark appearance, without specifying verified compatibility or quantity. Follow product care instructions rather than reproducing an unverified method.

Detailed shape is a strength; a loose main channel, poorly usable secondary, balance and tackiness are limitations. Final recommendation: 2 stars, without lifespan, certification or general realism findings.
