Sultry delivers deep, rumbly vibration through a rounded head that sits flush against the skin. A flexible neck lets you shift the angle without having to reposition your whole grip, which makes a real difference mid-use.

Flip it around and the tapered shaft rotates in a continuous 360-degree motion. It also warms up as it runs, reaching a gentle heat that adds a natural, comfortable quality to the sensation. The silicone is smooth and soft against the skin. The crystal-style button sits at the base and steps through the settings with a single press. At 20.6 cm long with a 5.08 cm diameter, it has enough presence to feel substantial without being unwieldy.

The warming rotation is the thing that sets it apart from most dual-ended massagers in this range. It's USB rechargeable with up to 1.5 hours of use from a 2.5 hour charge, waterproof, and includes a travel-lock. To toggle the travel-lock, switch the device off and press the main button three times in quick succession. The same action locks and unlocks it.
