Smart Water 水瓶升級套件

Snapped this onto my old 28mm bottle and it fits perfectly, no leaks so far. The silicone band is a nice touch for grip when my hands are wet from the gym. I honestly didn't expect the light blue band to glow as bright as it does at night.

The glow-in-the-dark band actually works, which I didn't expect to care about until I was fumbling for water at 2am. It screwed right onto my old 28mm bottle with no leaking, and the silicone band gives me something to grip when my hands are wet.

The snap-top lid is genuinely one-handed easy, which I didn't expect for a replacement cap. And that silicone band? Glow in the dark is a nice touch for finding my bottle in the car at night.
