Nothing but problems
I bought this ring simply because I didn’t want to have to pay $6 a month for my information. Boy was that a mistake. I had had it for about two months when it stopped connecting to Bluetooth I should’ve just returned it for good at that point. I filed with their warranty and they sent me a new one. Fast forward to today 6 months into having the ring… it now dies within a matter of 4 hours. There is no customer service you have to write to their AI bot and they decide when to put you in touch with a senior support. Their AI bot told me I could get a refund and proceeded to steal my account details then say it wasn’t the bot. I am still waiting to be out in touch with one of their senior reps. So DO NOT BUY this ring. They’re also being sued by Oura.

Stay away!
Worked for a couple months, then stopped. Company did send a replacement, but now the replacement stopped working and the company won’t do anything because it’s past a year (original ring bought in April 2025 and it’s June 2026). I like the app features, but to pay all that money for a ring to be useless in a little over a year is not worth it.

Good while it lasted
Battery life would last maybe 4 days. I did love it when it worked. I bought it in January and it stopped working in May. I didn’t purchase a warranty so the company nor target can do anything to assist. I didn’t think it would stop working so fast! So if you purchase get the insurance on it!

Ring stopped working after 6 months. I am within the one year warranty but the AI customer service bot is hiding behind the “lawsuit” and refusing to send a refund. Don’t buy!!!

Faulty Tech - Spend Money Elsewhere
DO NOT BUY!!!! I had my ring for a year and loved it but started noticing issues with connecting. I keep it in great shape so it was a technology error. They replaced my ring but then that ring had issues within a month!! It’s unusable and they won’t replace it but they did offer me the ability to buy up to their new version?? Why would I do that when my ring broke?? Spend the extra money and buy an Oura Ring instead.

Bad cuetomer service and endless issues
I have had this ring for a year now. While the data is cool, it’s functioned properly for no more than 90 days all year. It was constantly struggling to connect, needing factory resets (losing all your data and trends) and now it won’t connect at all because the battery won’t hold charge and the company says they can’t help me because I’m one month over the one year warranty. Not to worry because they suggested when I buy a new one, if I get their upgraded subscription, I’ll have better coverage…. I won’t be buying another Ultrahuman. Go with the trusted brand!

Good tracking
[This review was collected as part of a promotion.] Great device for those who are interested to track daily habits and especially when going to gym and tracking training goals. Can easily connect to my phone, easy to use when it comes to tracking heart rate, blood flow. Besides helps location capture and additional biomaker data. It's perfect tool to track your health and understand it's needs. Lightweight and great design

Buyer beware
The ring started off great upon purchase, however after less than 5 months of use it stopped connecting to the app and was useless. I have been in contact with customer service and they only recommend replacements which also are not connecting.

Dont buy save your money
They send me a replacement with in the first year and now the replacement is garbage 4 months later and they won’t do anything about it so beyond upset that ultra human doesn’t care about the people who spend their hard earned money on their products.

DO NOT PURCHASE This ring is extremly defective and Target will do NOTHING to help you rectify the issue. I had my ring less than 60 days before it would not hold a full charge for even a single day. When reaching out to Target they said it was out of the 30 day window for returns or refunds. Target has a normal 90 day policy but for some reason this item they only give 30 days too. When I bought up the 1 year warranty they said I needed to take it up with the manufacturer. Target is banking on the ring failing only after 30 days and not even guarenteeing it for 90 like all other electronics. Buyer bewhere!

Only lasted 1 year
[This review was collected as part of a promotion.] After only a year my battery is expanding and therefore the ring is no longer safe to wear

Stopped working after 2 months
[This review was collected as part of a promotion.] Stopped sending data to my app after about 2 months of use and the battery dies after a few hours - doesn’t last a full night. I tried resetting it, followed all of the prompts, but nothing will fix it. Basically completely useless and a total waste of money.

Genuinely awful. Lasted maybe 3 months before the battery completely stopped holding a charge. Customer service has not been helpful.

Battery dies quick. No replacement No support. No return. Do not buy
The ring is defective with battery draining really fast after 3 months. However, since I purchased the ring past 2025 October, Ultrahuman no longer provides warranty or support for the product. They cannot provide a replacement. Also, Target only provided me with a manufacturer number that no one pick up, and refuses to let me return the defective product. Don't buy this!!!
