Allows depth of penetration to be adjusted externally and gradually, without needing to stop or change position, which may help with pain, sensitivity, or fatigue during penetrative sex
No internal fitting or insertion is required, so it can be added or removed easily by either partner
May suit people managing conditions where deep penetration is uncomfortable or needs to be limited, including after surgery, during recovery, or with ongoing pelvic pain
Has no buttons, batteries or settings to manage, which may suit people who prefer a simple, low-tech option or find electronic interfaces difficult to navigate
Soft and skin-like against the body, which may help where texture or sensory sensitivity affects comfort during penetration
Can be used with a partner's own body or with a toy, so it doesn't require replacing existing equipment

Wash the rings with warm water and a mild soap, or a water-based toy cleaner, before and after each use. Allow to air dry fully before storing in the travel pouch. If the rings feel too tight, they can be stretched by wrapping them around a wide object, such as a water bottle, for a few hours.
