The rumbly vibrations on this thing are no joke, way deeper than the plastic one I had before. The reinforced metal shaft gives it a nice weighty feel in the hand, and the charge actually lasts through a full session.

I was worried the metal body would feel cold, but it warms up fast and the rumble is way deeper than my old plastic one. The reinforced shaft makes the vibrations feel steady instead of buzzy, and I only have to charge it maybe once a week.

The metal shaft gives it a heft that makes the rumbly vibrations feel deeper than any plastic one I've tried. Battery easily lasts a week between charges, and the steadily low hum means I can actually use it without the whole apartment knowing.
