Ensure the Perfect Fit Before Ordering Your LYNX Smart Ring

Take the guesswork out of smart ring sizing with the RENPHO LYNX Smart Ring Sizing Kit. Designed specifically for the RENPHO LYNX Smart Ring, this sizing kit helps you accurately determine the ideal ring size before purchasing your smart ring, ensuring maximum comfort, accurate sensor performance, and all-day wearability.

Unlike traditional ring sizes, LYNX Smart Ring sizes differ from standard sizing systems. This dedicated sizing kit allows you to test multiple sizes in real-world conditions before placing your final smart ring order.

Designed Specifically for LYNX Smart Ring Sizes

The RENPHO LYNX Smart Ring uses its own sizing system, which differs from standard US ring sizes. The sizing kit provides accurately matched sample rings that replicate the sizing of the actual smart ring, helping users confidently select the correct size before ordering.


Includes 8 Sample Ring Sizes

The kit contains eight sizing rings, allowing users to test multiple sizes and identify the most comfortable and secure fit.

By trying different sizes throughout the day, users can determine which option provides the ideal balance between comfort and sensor contact for accurate health tracking.


Optimised for Accurate Health Tracking

Smart rings rely on consistent skin contact for accurate biometric monitoring. Proper sizing helps improve performance across health and wellness tracking features such as:

  • Heart rate monitoring
  • Sleep tracking
  • Blood oxygen monitoring
  • Activity tracking
  • Stress monitoring
  • Recovery insights

A correctly fitted smart ring helps maintain reliable sensor contact throughout daily wear and sleep.


Test Your Fit Before You Buy

RENPHO recommends wearing the sample ring for at least 24 hours, including during sleep, to evaluate comfort and fit under real-life conditions.

This allows users to experience how the ring feels throughout the day as fingers naturally expand and contract due to temperature, activity levels, and hydration changes.

Community discussions around smart rings also recommend extended wear testing before choosing a final size, as finger size can vary throughout the day.


Ideal Finger Placement Testing

The sizing kit helps users determine the best finger placement for the future smart ring. RENPHO recommends testing on:

  • Index finger
  • Middle finger
  • Ring finger

This helps users identify which finger provides the most comfortable fit and optimal sensor positioning for long-term wear.


Comfortable All-Day Wear Assessment

The sizing rings are designed to simulate the fit of the actual LYNX Smart Ring, allowing users to assess:

  • Comfort during daily activities
  • Sleep wearability
  • Finger swelling changes
  • Exercise and movement comfort
  • Long-term fit consistency

A properly sized smart ring should feel secure without being restrictive or uncomfortable.


Sizing Kit Refund Programme

After purchasing both the sizing kit and the LYNX Smart Ring, RENPHO offers a sizing kit refund process through their customer support team, helping customers confidently determine their size before committing to the full smart ring purchase.

  • Return of merchandise (RMA) and Warranty

    We want you to be happy with the purchase you have made from us. If you are not completely satisfied, you may return the product to us and we will either refund, credit, repair/replace it, subject to the below terms and conditions. 

    You can return purchases for a refund (excl shipping). Please notify us within 7 days and ensure item is ready maximum 10 days after delivery date.

    Please ensure to log your return request within 7 days of receipt of your item. Please ensure to select the correct reason for return:

    - Changed my mind / Item exchange

    - Faulty on arrival

    - Incorrect item received

    All items are covered by a 12 month warranty (unless otherwise stated) which will be honoured directly by GeeWiz. All products will either be replaced/repaired/refunded depending on stock availability. Products will require evaluation by GeeWiz before a warranty claim can be accepted.

    Should the item being returned for assessment be found to be in good working order, unfortunately, there will be a collection fee that will apply.

    The collection fees are as follows:

    - For returns on items that were sent with free shipping: R198

    - For returns that had a surcharge, the same surcharge will apply for collection.

    Please log your return on your account, under the returns manager.

    We do not reimburse your fee to ship to us, but we will pay for return shipping if the item is subject to replacement. If the item you wish to return was ordered incorrectly / is no longer required / you have changed your mind, there is a collection fee that will be charged (please refer to the above) and this will be deducted from the refund amount once the supplier has credited us. Please note GeeWiz will only cover return shipping of a faulty unit within 6 months of purchase, after which, a shipping fee (starting from R198) will be applicable to you for the return of the unit.

    Any disputes relating to ordered items being short/incorrectly shipped will only be entertained if reported to GeeWiz within 3 days of delivery/collection.

    Refunds are subject to inspection of item(s) - in some cases, items will need to be sent to supplier for evaluation and testing. This can take up to 15 working days. Once a refund has been approved, this may take 3 - 5 business days to be processed.

    ALL returns are subject to up to a 30% restocking fee if item is no longer in BRAND NEW condition or if item seal/packaging has been broken.

    Please re-package safely and include all original product packaging.  

    All software products are unfortunately not eligible for credit or refund once purchased.

    After the 6-month period, you will no longer be eligible and won't be able to receive a refund. We can however replace or repair depending on the outcome after our team of professionals has inspected the product.

    Should a warranty sticker not be present on an item, the warranty is immediately null and void.

    Batteries are covered under warranty, but please note that GEL, AGM and LEAD ACID have limited cycle runs. These are typically around 200 cycles and may run out before the end of the warranty. Once the cycles have been depleted, it means the battery has reached the end of life and will no longer be a warranty claim.

    GeeWiz reserves the right to refuse a refund if the item is damaged from misuse, items are missing, or if the product is altered in any way. 

    GeeWiz or its affiliates are not responsible for damage or loss of any kind that may occur as a result of using or misusing any product purchased from us.
