Screaming O 4B 深層轟鳴子彈 葡萄色

The grape color is prettier in person, and the soft PU coating makes it feel almost velvety. That low-pitch rumble is no joke—it’s surprisingly deep for something so compact, and the 30-minute battery held up through two sessions.

Was pleasantly surprised by how deep the rumbling feels despite its tiny size—the pulse pattern is my favorite setting. It’s completely waterproof, which makes cleanup a breeze after a long shower session.

The grape scent is subtle but nice, and that deep rumbling vibration is no joke—it gets right under your skin. It's waterproof too, so I've taken it in the shower without a worry. Battery life held through a few sessions, which surprised me for something this small.
