I purchased a Lumen device approximately three years ago and never opened the box, downloaded the app, activated my account, or used the service. I recently discovered that I had been charged approximately $20 per month for the associated membership for about three years. When I attempted to cancel, I had to download the app solely for that purpose. After navigating to the cancellation option, I received an error message and was redirected to customer support. Customer support ultimately canceled the subscription, but I was disappointed to learn that recurring charges had continued for years on an account that I never activated or used. I have requested information regarding any activation or usage associated with my account. My recommendation is that Lumen make recurring subscription terms more prominent, provide clearer billing notifications, and offer a straightforward self-service cancellation process that functions properly.
Hi Chris, Thank you for sharing your experience. We would like to clarify a few points for readers. The Lumen membership is included with the purchase and is disclosed prior to checkout and in our Terms of Use. Memberships begin upon device delivery or 10 days after purchase. We would also like to clarify that downloading the app was not required to contact us or request cancellation. Customers can reach our support team through multiple channels, including the Contact Us page on our website. Regarding your cancellation request, our records show that your chat was opened at 11:03 AM and your membership was successfully canceled by 11:15 AM during the same interaction. We appreciate your feedback regarding subscription visibility and the cancellation experience. We continuously review customer feedback to improve our products and services, and we thank you for taking the time to share your perspective. All the best, The Lumen Team
I was highly skeptical. I am a believer. Lumen is a great tool. It could use some improvements in several areas but overall it’s the best way to keep an eye on your progress

I have contacted Lumen customer service multiple times. Ultimately their customer service is excellent but there is a delay getting connected with a representative. I give the representatives themselves and resolution 5 stars, but 4 stars because I initially have to wait a week to hear from them or contact them twice before getting any reply.

UPDATE: June 22, 2026 now weighing in at 142 if you're still skeptical, sitting on the fence, make the leap get your own Lumen!

Update to original review: lumen reached out and they were able to help me with Customs pretty quickly. They were very kind, and I am very satisfied with the outcome. I still think they should have a better system for accessing this service. But the service, once accessed, was stellar. Original review: Customer service is not helping me with an order stuck in customs. There is no phone number. I was told by a bot that a human would contact me, but not when, and it’s been a while. I am very upset with this poor service.
Hi Ma, Thank you for sharing your feedback. We're sorry to hear about the delay with your order and understand how frustrating it can be when a shipment is held in customs longer than expected. While customs processing is unfortunately outside of our direct control, we recognize the importance of keeping customers informed and supported throughout the process. We've sent a request for your personal details so we can look into this matter for you. Thank you for your time! All the best, The Lumen Team

Hi Janella, Thanks for the 5-star review! We’re so happy to hear you're enjoying the insights Lumen is providing you! Keep up the great work :) All the best, The Lumen Team
It was not clear that using the lumen device would generate monthly fees of $20+/month. Discontinuing that makes the device itself unusable. Communicating with customer service was atrocious. This is as close to a scam as I have ever experienced.
Hi Shannon, Thank you for your review, and we apologize for this experience. The Lumen device comes with a membership option that is selected at checkout, and you can turn off auto-renewal if you do not wish to continue the membership. Even without an active membership, you should still be able to use your Lumen device to take unlimited breath measurements. Unfortunately, we cannot locate your contact details using the information provided on TrustPilot. We have submitted a request for your information and look forward to speaking with you. All the best, The Lumen Team
Good customer service. Quick response. All went well.

We’re so glad to hear that Lumen has become a valuable part of your routine and that the combination of metabolic insights, nutrition, and exercise guidance is helping you stay on track toward your goals.
