Customer photo review of Control Ring™ for Juvederm® Syringe | 10-Pack

Loving the ease of aspiration with maintaining my position 😌!

Control Ring™ for Juvederm® Syringe | 10-Pack

Store owner replied: Thank you so much Xavier! We're excited to know that your custom size Control Rings have been treating you well! Love the picture too :)

I have big hands so it would be nice if there were a bigger size but it’s ok.

Control Ring™ for Juvederm® Syringe | 10-Pack

Store owner replied: Hi Jennifer, Thank you for the great review! It appears you ordered the Standard (ST) size thumb loop of the Control Ring for Juvederm syringes. We offer a total of 6 sizes for all of our Control Ring models. 3 of those sizes are larger than our standard (ST) size. I'm confident one of them will fit you more than ok! I'll send you an email, so we can set you up with our Fit Kit to find the proper sized thumb loop for you!

Perfect. I am so happy with thus idea. It makes work easier.

Control Ring™ Fit Kit

Love my control ring. I’m a newer injector and have small hands and this allows me to have better control of the plunger so that I’m always ready to inject or aspirate at the exact moment I need to. Instead of thumbing around for the other end of the syringe, I’ve got it attached to me so it’s one less thing I need to keep eyes on. It has given me peace of mind knowing I can be a little bit more steady, especially while aspirating. Thank you KA Designs 🙏

Store owner replied: Thank you Kara, we love to hear that the Extra Small Control Ring is treating you well and just the fit you were looking for! Honestly it always makes us extra happy when customers like you benefit from our custom sizing, we know there aren't a lot of options when you've got small hands :)

Great idea Great product Do you have for 3cc for PRP injections?

Store owner replied: Thanks for the review, J! Great timing - David is currently developing a couple 3cc models. We love getting feedback from our users early on, so if you're interested in being a beta tester, drop David an email at David@ControlRings.com. He’d be happy to hear from you!

They work really well. Love being able to aspirate with one hand and keep the needle stable.

Control Ring™ for Restylane CONTOUR®, DEFYNE®, KYSSE®, REFYNE® Syringe Aspirator | 10-Pack

Store owner replied: That is exactly what we love to hear! One-handed aspiration is a total game-changer for stability, and we’re so glad our Control Rings are helping you keep things steady and precise. Thanks for sharing your experience!

I would love to show you the use of these Control Rings "in action" but... I use them for Trimix injections so those photos would not be appropriate. Aside of that, they work great and you should also advertise that these Control Rings work very, very well with administrating these mens health injections due to the fact that you have to asperate some blood into the syringe to ensure that you are entered into the corpus cavernosum. These really do work very well. There is "NOTHING" made commercially at all! An addition of two more rings or a bar at the syringe top would also help as well.

Store owner replied: We completely understand - we’ll definitely take your word for it on the 'in-action' shots! It’s incredibly helpful to hear how the rings are making a difference for men's health and the specific precision needed for aspiration in that process. We also really appreciate the feedback on the design additions; we're always looking for ways to evolve. Thank you for the support and the great suggestion Paul!

We were absolutely delighted with the control rings size kit that KA Control Rings sent to us for our graduates completing their mastery training with Dr Tim. The quality was excellent, and the size kit was perfect for our needs. Our delegates genuinely loved them, and they made such lovely little gifts to hand out at the end of the training. The kits were very well received and added a thoughtful, professional touch to the graduation experience. We wouldn’t hesitate to recommend KA Control Rings.

Store owner replied: It is such an honor to be a small part of your graduation experience! We’re thrilled to hear that the size kits resonated so well with Dr. Tim’s graduates and added that extra professional touch to their milestone.

Control Ring™ for Juvederm® Syringe | 10-Pack

Store owner replied: We love this review Irene! Thank you for trusting with the care and mastery that you bring to your clients :)

I have not had a chance to use the product yet, however, my five star review is based on the customer service. I was not aware that versa came in two different size syringes and when I ordered the 10 pack, the company automatically sent me both versions of the adapter ring so that I would have a working product either way. I thought that was great initiative on their part to ensure I was happy as a customer and look forward to trying their products in the near future thanks again!

Love this new device and I love the personal note that came along with my order!

Revanesse® Syringe Aspirator | Control Ring™ - 10 Pack

Store owner replied: Thank you Christina! This is a very personal endeavor for us, and it means the world to have your support!

I've tried a few of these types of devices, and usually they are awkward and distracting to use. Constantly adjusting them is a distraction. The best compliment I can give, is that I only think about the k ring when it's not there. Every injector should use these for safety and convenience.

Juvederm® Syringe Aspirator | Control Ring™ - 10 Pack

Store owner replied: Thank you for your thoughtful feedback Tim. We’re thrilled to hear such a compliment—that’s exactly what we aim for. Your recommendation means so much, and we’re honored to be a part of your practice!

I had ordered a set of rings, but I am in Canada, and I believe that the syringes up here may be slightly different than in the United States. As a result, my ring didn’t fit my syringes, But the team was quick to resolve the issue and sent me the correct rings! Amazing customer service, and now I have the right product!

Teoxane RHA® Syringe Aspirator | Control Ring™ - 10 Pack

Your safety and satisfaction are super important to us. Please do check your inbox when you have a moment. We’re here to make sure everything is sorted out to your satisfaction.

FAQs

Please read our FAQs page to find out more.

Q1: Are Control Rings reusable?

Control Rings are engineered for strength and precision.

Best practice is single-patient use, ensuring the highest standards of hygiene, clinical care, and patient trust. However, we recognize that not every injector setting allows strict single-use. For those cases, we provide a sanitation guide to support responsible, safe reuse when appropriate. Many injectors reuse their rings for 3–5 sessions or more, depending on handling, sanitation, and professional discretion. Control Rings are physically resilient — but your clinical excellence, patient trust, and professional standards always come first.

Q2: Will the Control Ring fit my syringe model?

Each Control Ring is custom-matched to specific syringe platforms — no adjustments, no guessing. Choose your preferred brand during ordering for a precision fit.

Q3: How does the Control Ring attach to the syringe?

Snap-fit attachment. No tools. No recalibration. It automatically self-centers on the thumb depressor for immediate use.

Q4: Does it affect how the syringe feels in my hand?

No — by design. The Control Ring preserves your syringe’s native ergonomics, weight balance, and tactile feedback while adding intuitive one-handed aspiration support.

Q5: What if my syringe designs change in the future?

KA Design's Control Ring Collection is built to evolve alongside injectors. We monitor syringe platform changes continuously and develop updated Control Rings to ensure continuity, precision, and future-proof performance.

Q6: What are Control Rings made of?

Control Rings are made from a premium PLA-based polymer, chosen for its high strength-to-weight ratio and durability. Every element has been distilled to the essentials — eliminating unnecessary bulk or weight — to deliver unwavering stability, balance, and precision in the injector’s hand.

Q7: Where are your products made?

Every Control Ring is designed, engineered, and produced in the United States.
