I was a bit skeptical about the head heating thing, but it actually makes a real difference—soothing and effective. The silicone body is smooth and easy to clean, plus the 10 vibration modes give plenty of variety. Definitely worth the money for the quality.

The heating feature warms up nicely in about a minute, which makes a real difference. Only gripe is the pinhole charger is a bit finicky to line up, but a full charge lasts through several sessions.
