Verified Purchase Reviews
"Waterproof, durable, stylish — checks heart rate, sleep tracking, menstrual cycle, and much more. Very comfortable! No subscription needed!! Honestly surprised by how accurate the sleep data is."
"The battery lasts several days on a single charge and I love that it's waterproof so I don't have to take it off constantly. The app is genuinely easy to use. Incredible value."
"It is sleek and looks very high end. I ordered a size 7 and it's true to size and fits perfectly! The battery lasts for days and it feels great to wear all day. Highly recommended!"
"The ring measures exactly. It has a very good app that reports very extensively. I compared the data with other health trackers. The data is all very close. Worth every cent."
"I track my sleep which is the reason I bought it. The battery life is great — lasts the whole week. Comfortable enough to wear through the night without noticing it. Exactly what I needed."
"The company clearly specialises in this tech and it shows. Very reasonable price for the feature set. I use it daily and the Aurora app gives me real health insights every morning."
"Fantastic entry point into smart ring tech. I find traditional smartwatches cumbersome for sleep tracking but still wanted to monitor activity — this is the perfect solution. Undeniably cool too."
"Battery easily lasts beyond a week of daily use. If you only use the sleep function it lasts even longer. Very energy efficient, packed with features. Hard to fault it at this price."
"Heart rate and step tracking accuracy are surprisingly good. Comfortable all day. No subscription fee is a massive win — I get all the data without a monthly bill. 10/10 would buy again."
"In conjunction with the Aurora app, this ring provides plenty of health and fitness information. Monitoring heart rate, oxygen, stress, sleep, and HRV. Recommended for anyone wanting detailed data."
"Great ring overall. The sleep and HRV data has been eye-opening. Four stars only because I wish the app synced with Apple Health — but for standalone use it's excellent. Will definitely keep wearing it."
"Pricing is unbeatable. You get genuine health tracking for the cost of a nice lunch. No other brand offers this functionality at this price. The battery is the real standout — just charge it once a week."
