The Linger

Press and hold the power button to turn the device on. Once running, a single press cycles through Low, Medium, and High intensity, then continues through all 7 vibration patterns. Press and hold again to power off.

Yes — The Linger is IPX7 waterproof, meaning it's fully submersible. Just make sure it's not being charged at the same time, and avoid activating controls while it's connected to power.

Use water-based lubricant only. Silicone-based lubricants are not compatible with silicone toys — they can cause the material to degrade over time.

Insert the charging pin gently into the silicone-covered port and connect to any standard 5V USB source. A full charge takes 120 minutes and delivers around 45 minutes of use. Always fully charge before first use.

Rinse with warm water and mild antibacterial soap after each use, then dry with a lint-free cloth. Never use alcohol, benzene, acetone, or other harsh solvents — they damage the silicone surface.

Always. All Serika orders ship in plain, unmarked packaging with no brand name or product description on the outside.
