6. Safety Information
- Toys used in the anus and rectum should not be used in the vagina to prevent bacterial transfer.
- When using insertion toys, be aware of the size of the toy versus the size and depth of intimate areas. It is possible to overstretch, tear, perforate, or otherwise injure intimate areas. Select products that are not too large or too small. Start with smaller toys and gradually increase size as experience grows.
- Warning: Insertion toys that do not have stops, rims, or retrieval devices can become lodged in the body and may require medical assistance for extraction. Injury to the vagina, anus, rectum, colon, and other body parts is possible, particularly with overly vigorous play or improperly sized toys. Users assume all risks of injury.
- Do not attempt to warm this product in a microwave or conventional oven.
- This product is intended for adult use only.

8. Troubleshooting
8.1 Suction Cup Not Holding
If the Vac-U-Lock suction cup is not adhering properly to a surface, consider the following:
- Ensure the surface is clean, smooth, and non-porous. Rough, textured, or dirty surfaces will prevent proper suction.
- Make sure the suction cup itself is clean and free of debris or lubricant residue.
- Press the suction cup firmly onto the surface, expelling as much air as possible.
- For heavy products, the suction cup may require a very flat, perfectly smooth surface to hold its weight.
