Rung cổ điển Concave

Wasn't sure about the concave design at first but it actually reaches spots my old one never did. The rounded shape feels smooth and not at all awkward to hold, and I like that it's not bulky. Genuinely surprised how quickly it became my go-to.

The rounded shape fits way better than my old straight one, and the concave curve actually reaches spots I didn't know I had. Quiet enough that I stopped worrying about roommates, too.

Wasn't sure about the concave design at first but it really does hit spots I didn't know existed. The rounded shape fits comfortably and the vibration is strong without being buzzy.
