1. Product Overview
The MOMAX 1-Sense Soul Smart Ring Sizing Kit is designed to help you determine the most comfortable and accurate size for your MOMAX Smart Ring before purchase. This kit is essential as MOMAX Smart Ring sizes differ from standard ring sizes. The kit includes various plastic rings (sizes 6-13) to ensure a precise fit. Please note that this kit contains sizing rings only; the MOMAX Smart Ring is sold separately.

2. Setup and Sizing Instructions
Follow these steps to accurately determine your MOMAX Smart Ring size:
- Select a Finger: The MOMAX Smart Ring can be worn on any finger of either hand. For optimal accuracy in health tracking, it is recommended to wear the smart ring on your left index or ring finger.
- Try Multiple Sizes: Experiment with the different plastic sizing rings provided in the kit. The ring should fit snugly over the largest part of your finger (e.g., your knuckle) but still be comfortable enough for daily wear without rotating freely.
- 24-Hour Wear Test: Finger size can fluctuate due to environmental factors and body weight. Wear your chosen sizing ring for at least 24 hours to confirm the perfect fit. The ideal fit is snug against your skin without causing discomfort or rotating excessively.
- Note on Materials: The sizing rings are made of plastic. The actual MOMAX Smart Ring is crafted from premium metal for enhanced comfort and durability. Therefore, the plastic sizers may feel less comfortable than the final product.

4. Care and Maintenance
4.1 Sizing Kit Care
- Keep the plastic sizing rings clean by wiping them with a soft, dry cloth.
- Store the sizing rings in their original packaging to prevent loss or damage.
- Avoid exposing the plastic rings to extreme heat or direct sunlight for prolonged periods.
4.2 Smart Ring Care (Reference)
- Water Resistance: The MOMAX Smart Ring is designed to be water-resistant, allowing you to swim, shower, or exercise without concern for damage.
- Cleaning: Clean the smart ring with a soft, damp cloth. Avoid harsh chemicals or abrasive materials.
- Charging: The smart ring charges quickly. A full charge typically takes around 40 minutes, and a 5-minute boost provides enough power for a full day of use.

5. Troubleshooting (Smart Ring Reference)
This section provides general troubleshooting tips for the MOMAX Smart Ring (not the sizing kit).
- Inaccurate Readings: Ensure the smart ring is worn snugly on the correct finger (left index or ring finger is recommended for optimal accuracy). The sensors on the inner surface of the ring should maintain consistent contact with your skin.
- Connectivity Issues: If the smart ring fails to connect to the MOMAX Sense App, ensure Bluetooth is enabled on your smartphone and the ring is sufficiently charged. Restarting both the app and the ring may resolve the issue.
- Charging Problems: Verify that the charging cable is securely connected to both the ring and a power source. Clean the magnetic charging port on the ring if necessary to ensure proper contact.
- App Not Displaying Data: Confirm that the ring is being worn for sufficient periods, especially during sleep, for the app to collect and display comprehensive data.
