Vòng Ohnut Rung

Really like that it fits right onto the buffer rings I already had — the setup took me less than a minute. The vibration is strong enough to notice but the motor's placement means it doesn't rattle awkwardly against anything. Only wish the battery life were a bit longer, but for the price it's a sol

The motor is surprisingly quiet for how strong the vibrations are, and it pairs seamlessly with the buffer rings I already had. Only downside is I wish the power button were a bit easier to find by feel mid-use, but once it’s on, it stays put.

The vibration is quiet enough not to be distracting, which I appreciate, and it stretches over the buffer ring without much fuss. Only gripe is the motor feels a bit buzzy rather than deep, so it's not quite the sensation I hoped for. Works fine for what it is, though.
