Vibro：子彈型電池盒

Ten batteries in one pack feels like overkill until you realize how fast your Bullet drains mid-session. I swapped one in and it fired right up, no fiddling with the cap or connection. Glad I stocked up so I'm never cut short again.

Ten in a pack means I can finally stop rationing my favorite sessions. The batteries last noticeably longer than the cheap ones I’d been buying, and the snug fit in the Bullet is a relief.

The 10-pack means I’ve got backups stashed everywhere—nightstand, gym bag, even my desk drawer for a quick afternoon pick-me-up. The batteries fit snug and last longer than the stock one did, so the buzz stays strong through the whole session.
