A step-by-step guide to setting up, wearing and cycling through the Selopa SURE THING's 10 suction and 10 vibration settings, with practical air pulsation toy tips and safety checks.

Quick answer

Load three AAA batteries, apply a little water-based lubricant to the silicone mouth, and start with the lowest suction and vibration settings before cycling upward one mode at a time. The Selopa SURE THING is splashproof, not waterproof, so keep it away from running water and clean it with a damp cloth.

Why the SURE THING feels different from a plain vibrator

The SURE THING pairs deep vibrations with suction pulses, so the sensation is a rhythmic pull-and-release rather than steady buzz. That combination can feel intense quickly, which is why the first session should be about mapping the two control channels separately: learn what suction alone does, then add vibration.

Because the toy is petite (11.1 cm tall, 4.1 cm deep and 3.0 cm wide), it sits close to the body and is easy to angle. The trade-off is that the smaller body leaves less room to grip, so a light hold and a little lubricant matter more than force.

Batteries, lubricant and placement before you switch on

The SURE THING runs on three AAA batteries, which are not included, so check you have them before you settle in. Use water-based lubricant only on the phthalate- and latex-free silicone; silicone-based lubes can degrade silicone surfaces over time.

Placement is the biggest variable. Rest the mouth of the toy against the clitoris with a light seal rather than pressing hard, and let the suction do the work. If the seal feels weak, adjust the angle instead of pushing down.

Step-by-step: setting up and using the SURE THING

Insert three AAA batteries correctly: Open the battery compartment and fit three AAA batteries, matching the polarity markings. Common mistake: forcing the compartment shut when a battery is reversed. Checkpoint: the toy should power on before you add lubricant. Keep a spare set of AAAs nearby so a session does not end mid-mode.
Apply a small amount of water-based lubricant: Put a pea-sized amount on the silicone mouth and a little on the skin. Common mistake: over-lubricating, which breaks the suction seal. Checkpoint: the mouth should feel slick, not dripping.
Start with suction only on the lowest setting: Switch on and cycle to the lowest suction speed before adding vibration. Common mistake: starting on a high pattern and mistaking intensity for pleasure. Checkpoint: you can hold the toy comfortably for 30 seconds before moving up.
Add vibration one speed at a time: Bring in the vibration channel at its lowest speed, then step up only when the current level feels steady rather than distracting. Common mistake: changing both channels at once, which makes it hard to tell what you like. Checkpoint: note the number of the setting you prefer. Write down your two favourite numbers so the next session starts there.
Adjust angle before increasing power: If suction feels weak or uncomfortable, tilt the toy slightly rather than pressing harder. Common mistake: pushing the mouth into the body, which can pinch and reduce the seal. Checkpoint: a light seal with a comfortable angle beats maximum power.
Clean with a damp cloth, not running water: Switch off, remove the batteries if you are storing the toy, and wipe the silicone with a damp cloth and toy cleaner. Common mistake: rinsing under the tap because the toy is splashproof, not waterproof. Checkpoint: the battery compartment stays dry. Let the toy air-dry fully before replacing the batteries.

Product facts

Selopa SURE THING - Black Vibrating & Sucking Stimulator: 10 suction speeds and patterns plus 10 vibrating speeds and patterns, made from phthalate- and latex-free silicone. Two independent 10-setting channels let you dial in suction and vibration separately instead of accepting one combined intensity.
