Agreed with many here about the non appearance of the Rizz ring. Especially disappointing as a previous user of Nightrider which I found helpful I was happy to invest in the promised ring. As indicated by others getting the size kit took time but arrived eventually. Many contacts with promises but no actual product delivery. I mail received end of Jan telling me it was being shipped next week. Guess what… no shipping info and no product They must be having a considerable laugh at the diabetic community.

I ordered the Rizz ring back in August of 2025. It’s now February of 2026 and I haven’t received it yet. I’ve contacted them multiple times demanding a refund but each time they say that it’s about to ship but ignore my refund request. It’s become obvious that this is nothing more than a scam company. Please avoid!!

Crappie company delays since July order was supposed to be sent by October again delays i am opting for a refund its been 2 weeks of my request and kept ignoring me. Cannot trust them . Product also looks like a scam the RISS RING. AVOID ...although they acknowledged refund I had to keep asking and being ignored and look at the other reviewers same story. Poor customer service and doubtful about the technology and people are not getting their items. Avoid cleaning clear hassle had they paid me when asked I would not have written this

I am sharing my experience to help other customers make an informed decision. Order 246592 involved the purchase of smart ring Rizz. As part of the process, I received a sizing sample rings box, which is normal and expected. However, the final product was never delivered. Multiple tracking numbers were generated for the shipping (after 2 months of delay) neither of which shows confirmed carrier acceptance or delivery. One appears stalled, the other last tracking was 2 weeks ago from JFK. The only shipment successfully delivered was the sizing sample using UPS in September. Despite this, a tracking related to a different shipment was provided to PayPal, which resulted in the case being closed, even though the final product had not been received. The order still appears as ON HOLD on the company website, and fast shipping (39 USD) was paid but not provided. I have repeatedly requested either delivery with proper express shipping or a refund, without resolution so far. This review reflects documented facts and my direct experience. UPDATE – December 30, 2025 Additional tracking was shared after this review, but the product has still not been delivered and fast shipping was not provided. The situation remains unresolved. 1-04-2026 In reply ad Ambrosya: Thank you for your reply. A refund does not resolve the core issue. The product itself does not work as expected, and this is the main problem — not just the delay or the communication. Receiving an item late is one thing. Receiving an item that simply doesn’t deliver what it promises is another. Your response focuses on logistics, but completely avoids addressing the actual performance and reliability of the product. From a customer’s perspective, this feels like a generic reply rather than a real attempt to take responsibility. I hope you will take this feedback seriously, because improving shipping is not enough if the product itself is not effective. In replay: Dear Ambrosia Team, Thank you for your reply. However, stating that the product “is functioning as intended” does not reflect my experience as a customer. A product should work reliably in real-world conditions, not only under ideal setup assumptions. If correct setup, specific conditions, or additional guidance are required to obtain basic functionality, this should be clearly communicated upfront. From my side, the issue was not a lack of willingness to use the product correctly, but the fact that the results did not match what was promised. Offering step-by-step support after the purchase does not change the initial experience, which was disappointing. At this point, my feedback remains the same: the problem is not just usability, but the overall reliability and consistency of the product in everyday use. I hope this helps you better understand the customer perspective. 3th april 2026 Dear Ambrosia Team, Thank you for your reply. I appreciate the acknowledgment, but I would like to clarify a few important points. The explanation related to setup, placement, or individual physiology does not align with my experience. I have tested the ring on different fingers and under normal usage conditions, and the results remain inconsistent. At the same time, I am currently using other sensors and another smart ring, all under the same conditions, and they provide stable and reliable data. This makes it unlikely that the issue is related to my physiology or usage. For this type of product, reliability should not depend on “ideal conditions” or extensive troubleshooting after purchase. It should work consistently in everyday use. I also find it important to highlight that this follow-up is happening several months after my initial experience, which impacts the overall perception of support and responsiveness. I remain open to testing improvements, but based on my experience so far, the core issue appears to be related to data reliability rather than setup or usage. Regards, Stefania BTW I have installed and tested the beta version of the app, but the same issues remain. At this point, it is possible that my specific unit is defective. However, I am not willing to spend additional money on returns or replacements, considering the initial cost of around €300 and the experience so far. For comparison, the same amount would cover several weeks of reliable measurements using dedicated sensors. I am fully aware that a smart ring cannot match the accuracy of a medical-grade sensor. However, I would expect at least consistent and regular readings. Currently, the data is irregular and unreliable — for example, multiple readings within a short time frame followed by long gaps of several hours — which makes the system difficult to trust in everyday use.

Just spoke with a rep of Ambrosia Systems about receiving continued SPAM email marketing from them which I have attempted to unsubscribe from on many occasions. The rep informed me that he had just removed me from their email database and then ended the conversation with 'If you want continue to live in stone age that is your wish. Ambrosia products are most advanced in the world.' Please, do yourself a favour, do not hand over any money or personal information to this company as they do not respect their customers wishes and now have become insulting.

I have reached out to this company twice about removing my email address from their marketing campaign. Both times they have said my email address was removed. However since this claim I have received at least 8 more SPAM emails from them. I have no intention of buying any of their products so what function does it achieve to keep sending me SPAM? Be careful if you give any of your personal information to this company as once they have it they will be in constant contact and you cannot do anything about it.

I received a spare part ambrosia blucon lid. The ridges are not flat. Its a used piece.Once the coin is used the ridges jut out. With multiple uses only this happens. If it's a fresh piece it wil be flat. Pls contact me I can share an image My email id : rohini.s20@gmail

I am reviewing Ambrosiasys NightRider again because I have not received a reply to two problems with this company. The biggest problem is that I purchased a waterproof NightRider on 11/03/2023. I had some problems with the batteries and connectivity. After trying several things it settled down and began giving good results. As of June 30, 2023, I have not received a reading. Problem: All new sensors suppled by my mail order pharmacy have expiration dates after 11/30/2023. If an item they sold no longer works as specified in their sales information, regardless if the NightRider connects, Ambrosiasys should give a full refund or exchange with one that works. As of now the NightRider I have is a piece of JUNK. Don’t waste your money. Customer service is nonexistent.
