The 10 functions are actually distinct, not just three speeds repeated with slight tweaks, and the rechargeable battery means I've stopped buying batteries entirely. It's compact enough to toss in a toiletry bag for travel.

Didn't expect much from such a tiny bullet, but the 10 functions actually feel different instead of just buzzing at one speed. The rechargeable part is a big plus too, no hunting for batteries.

Tossed it in my carry-on for a weekend trip and it barely took up any space, which is exactly what I wanted. The ten settings give plenty of variety and the rechargeable part means no scrambling for batteries.
