User reviews

Hunk of junk

Now it’s asking for a code that it won’t accept. It wants a subscription or it refuses to work. I didn’t lose any weight anyways. I’ll stop using it. Checking my measurements was a chore I should have given up on a year ago. Waste of $400 bucks.

Be aware

I bought the product as a gift and liked the product initially but over a couple of months stopped using it.
Then, I was charged $240 auto renewal fee. Be aware.

Turns out that a very scamy notice was sent to me - “exciting 12 month ahead with lumen”. Not renewal is coming.
I am disputing the charge and feel very differently about the brand.
Also, suddenly the support center isn’t answering.

Works every tenth time

I can’t get it to work after trying to breathe in and out for 5-10 times. It gives an error or tells you to keep breathing or breathing out so much that your lung volume can’t handle it.

Absolutely junk

It doesn’t actually work it just gives you meaningless numbers that completely trash your digestion. Nothing but snake oil

Possible Security Problem

I received a lumen as a gift. I never signed on to a plan. I used it to take readings periodically, then stopped for a few months. I tried to get on today and could not. I downloaded again from the App Store in case I needed an update, received an OPEN, and could connect BUT
TO SOMEONE ELSES LUMEN. I have that person’s name
And address. First name Dana, second name ends in e. I could see what the Bluetooth was connected to and saw what it was not connected to. I STOPPED. Not a hacker. I wonder what a hacker could do!
Waiting to reconnect.
