### 1/5 — Terrible app

*2026-01-30*

This mask has to be reprogrammed every single night . Has bugs in the software, and is not intuitive to program.

### 1/5 — Doesn’t work, refunding the mask

*2025-12-22*

The mask doesn’t connect at all, even after deleting and reinstalling. This is a horrible app / product.

### 1/5 — Don’t Buy

*2025-06-06*

First, it’s not worth a trial as they don’t refund the whole thing if you don’t like it. They charge you $40 for the sleep mask part that probably cost them $2 from China. 
Second, as others have mentioned, the straps used to keep it secure are insanely bad. They are supposed to partially go over top the ear but this results in bruised ears if you do anything but sleep on your back. There are much more comfortable sleep masks that do not cause pain. 
Third, I was never able to get to actually use the features of it due to the pain this caused (tried for two nights but after restless sleep hours in had to get rid of it) the functionality is very jumbled. The app isn’t setup well at all. It feels like you are starting over every time you login. It asks what you want to do and you answer questions then pick a program. But if you want to do something else that might then it tells you there’s already a program and you can combine or delete it. What does combining do? Don’t know as it never says. As far as I can tell, all it does is shine light in your face at certain times that you would be awake. It also asked me if I shined light in my face on my own so it could know if I needed more I guess? Huge waste of money. The positives are probably paid as there aren’t many. Avoid this product and the company. There’s a reason they haven’t posted anything new in months on their blog. They do a once a month update on the application to keep it looking active. But you’ll notice they all just say bug fixes. I was scammed. Don’t be scammed yourself.

### 1/5 — Expensive, Uncomfortable, and Not Premium-Feeling

*2025-06-01*

For $299, you get an uncomfortable mask that does not have a premium feel. The string cut into my ears and the mask was not large enough or contoured enough to black out all the light. The app was a confusing mess. I ended up pitching mine in the trash in favor of a silk sleep mask.

### 1/5 — Waste of $300

*2025-05-29*

Bought a sleep mask just to find out that not only is the app not available on my new phone due to it not being available on Android, but also that the IOS app crashes itself every time I try to enter a birthday, gender, and eye color, all of which is already irrelevant information to ask for, and has no option to skip. I straight up got scammed out of almost $300. Screw you Lumos. Avoid their products at all costs.

### 1/5 — Terrible with IOS

*2024-11-25*

Lumos Sleeo may be a good product when it works but it does not work well with IOS. I contacted the company and they agreed!  I have to erase the app and download it again every time to have it connect which what the company told me to do. A terrible product for IOS users.

### 5/5 — The best sleep ever!!

*2024-09-25*

I have been using a wake-up clock for years so using a sleeping mask was always a no go. 

I love waking up naturally with no loud alarms. Summer sunrises are very early so my sleep pattern would be destroyed. I would be yawning and tired because my clock was set to 6:30 but the sun had its own plan. 

Then I discovered Lumos. I could block out the light and still get a sunrise waking.  

I am a heavy sleeper, so when I started using Lumos, and was surprised when I got even better sleep!! 

This product has many features, like shifting your body to the time zone you are traveling too. 

I recommend this product even if you think you sleep well. You might be surprised like I was.

Support is awesome. I got help and they said they would add a feature I suggested!!

### 5/5 — A lifesaver for circadian alignment

*2024-06-28*

This product is a game changer for my jet lag. The science behind it is super interesting, and I love that they are making a device based on circadian rhythm alignment. There’s also a number of new features that I’m excited to try—like the sunrise alarm. The app is actually fairly intuitive for how high tech this product is. Overall, love the product!

### 5/5 — Great customer service

*2024-06-28*

Other than I never have jet lag when I use the sleep mask, I submitted a feature request to use the mask on the airplane. Not only did they respond promptly, they added the feature. Wow, wish more companies were like Lumos!

### 5/5 — No jet lag!!

*2024-06-28*

A friend of mine told be about Lumos so I decided to give a try. I borrowed their mask for a recent trip to Rome and was amazed...no jet lag!! Slept through the night when I arrive and when I returned. I order a mask of my own. Simply amazing.
