FLIP ZERO GRAVITY EV（電子振動）黑色

Didn't expect the vibrations to carry this well through the whole thing — you feel it top to bottom, not just in one spot. The densely packed detail on the inside makes fast strokes feel way more intense than I figured. Solid buy.

The firm material feels solid in the hand, not flimsy like my last one, and the densely packed texture really does make fast strokes feel smooth. Honestly didn't expect the vibrations to carry through the whole thing so evenly.

The vibrations are way stronger than I expected and I can actually feel them through the whole thing, not just at the tip. The densely packed details give the strokes a really smooth feel, and the firm build means it doesn't rattle around.
