How to measure your finger size
Step 1: With a strip of paper or a thread place it between your fingers.
Step 2: Wrap it with enough tightness that it is a snug fit but not so much that it restricts your blood flow.
Step 3: Mark the lines where the thread/paper meet.
Step 4: Measure the distance between the marked lines on a scale. That's your circumference.
Step 5: Compare it the sizing chart to know your ring size.
I love it. Super cute. And it does checks throughout they day and keeps track of everything on an easy to use app.
I love my ring. I really didn’t think it would work this good but it’s great. I am afraid to get it wet. I don’t know if it will ruin it. I don’t want to take a chance.
I love the info I'm receiving from this ring. My only "complaint" would be that the Leaderboard was nothing but Chinese names (as if I had signed in from China), but I'm from the USA. The instructions did not give more than "turning it on basics". After I did a "reset", by random, it changed. A more indepth instruction booklet would have been helpful.
I’m really impressed with this lightweight Bluetooth smart ring. It’s incredibly comfortable to wear all day, and I often forget it’s even on. The connectivity is fast and reliable, syncing smoothly with my phone without any hassle. The design is super cute, and the battery life is surprisingly good for such a compact device. Overall, it’s a smart, stylish, and convenient piece of tech that fits seamlessly into everyday life.
I loved it. It’s comfortable, you can barely feel it when you walk, and it works perfectly.
Like it
This ring is exactly what I needed—it's adorable
Dos not hold a charge at all
Thank you for letting us know. We're sorry to hear about the battery issue. The ring should not be losing its charge abnormally quickly during normal use. We'd like to check what is happening and help resolve this for you. Please contact our support team with your order number and let us know approximately how long the ring lasts after a full 100% charge. If there is an issue with the battery, we'll make sure to help you with a solution.
Great. Just ordered wrong size.
Beautiful enamel ring
Doesn't always connect. I have to take the ring off and put it back on to get measurements.
Less than a day and already glitching in sync. Looks good though.
Love it!!! Have received so many compliments on this ring!!!!
Super j'adore!
Just received my ring can’t wait to get started
I love the ring i wish i ordered it for another finger though but im loving it.
Cute and comfortable! Tracks my sleep, my steps and my overall health and mental well-being. I love this.
I just got it today. I am so excited to try it out. 😊
Beaucoup de difficulté à garder sa charge.
I love it!! It's pretty and works great to track sleep and more!!
Beautiful ring However I ordered a bit small so didn’t fit Customer service was excellent and offered to exchange but postage not suitable from uk So ordered a larger size and price was reduced by 50%
My purchase with Wrongduck was very positive. The quality, look and the working of the ring was as described and the shipping time was quicker than expected.
I ordered the wrong size and the team worked hard to sort the issue out. The whole way through they kept the very best interest of the customer (me) as a priority.
They worked closely with me throughout the entire process to ensure the outcome was positive.
Thanks Wrongduck team! Keep up the hard work and I will definitely be back
Teally like this ring..really attractive
So far I love it, it’s so cute, and I’m happy I can see my health in real time and not wait until I go to the doctor:)
Keeps a long charge. And very easy to load app.
I wear this ring every day, and it remains incredibly comfortable even with extended wear. The butterfly floral design is stunningly beautiful.
Love it! Inexpensive? Syncs with my iPhone. Great buy!
At first, I was concerned about comfort, but this smart ring feels incredibly comfortable on my finger. Wearing it all day causes no discomfort whatsoever. The setup process was quick and easy, and all features work perfectly.
