ULTRAHUMANRing AIR - Aster Black - Size 5 - Smart Ring | No Monthly Subscription | Size First with Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker

Super pleased with the ultrahuman ring, the stats are so accurate and it really helps me to understand my body more. The charging speed is super quick so if it is ever low of power it doesn’t take very low at all to charge it. The battery life is great it’s lasted me 5 days before I’ve needed to charge it. Since wearing it for a nearly a couple of weeks now it’s become so comfy and I couldn’t be happier with it! If you’re stuck between choosing this or the Oura ring definitely choose the ultrahuman it’s way better and so worth the money I’m so so pleased.

Really happy with this ring – it’s super comfortable, looks great, and the sleep and recovery tracking feels very accurate. Battery lasts several days and charges fast. Much nicer to wear than a bulky watch.

I bought this fitness ring after doing a lot of research, and overall, I’m quite happy with it. I wanted a sleek tracker I could wear daily, and this one ticked most of the boxes—especially the fact that it doesn’t require a subscription.The sleep tracking is one of my favourite features. It gives detailed insights that seem accurate and useful. Step count and heart rate monitoring also appear reliable, which helps me keep track of my overall activity and recovery.I chose the rose gold version because all my jewellery is rose gold, but in hindsight, the brushed finish gives it a slightly different tone, so I probably should have gone with the regular gold for a closer match to my other pieces.

I’ve been using the ring for around 10 months now, I mainly bought the ring for sleep tracking however this does not track very well at all, there’s times when I am at work and the ring reports that as a nap because I’ve been sat still on a conference call, same when watching TV in an evening. I bought to replace wearing me Apple Watch to bed, however when wearing both devices to bed, the results in a morning are miles apart, I would tend to trust the data much more from the Apple Watch then the ring itself, the ring will record 7 hours solid sleep when I’ve been to the toilet in the middle of the night or the dog as woken me, both of which would show on the watch.The ring now is unusable, as the plastic inner has changed shape so no longer able to charge the ring itself, I have reached out to ultrahuman, so just awaiting a response.I was wearing the ring itself on my wedding ring finger, maybe wearing on another finger would have different results, but all in all, complete waste of data and money for myself.Update.It appears the battery itself failed and has swollen, I have reached out to ultrahuman support whom have been extremely slow to respond and asked to send a video which I have done, from this video you can see the battery issue and all now gone quiet from Ultrahuman since this video was sent to their support team, luckily Amazon have offered a full refund.

After research i thought this ring was best, the app is amazing and useful rather than just a data collection tool. The analytics are great and very comfortable to wear, battery life around 5 to 6 days.

Complicated app and not all free as has been advertised in the description, easy to show signs of wear and tear, some glitch in sync and download data, not the same data as the other sync apps.

It's a good ring, and it offers features that the other brands don't. They are always innovating and that's surely a good thing. They have very responsive customer chat service in the app and will send replacement rings out when things go wrong. But this is where my review gets the poor rating. I'm on my third ring in five months, one day they are fine and then Ultrahuman push out a firmware update...all seems well and then a few hours later its dead and no amount of tapping and recharging can wake it up. Support will claim this is extremely rare, but it happened twice to me, and looking a reddit reviews, its happened to others too. They need to review their test procedures and they release so many updates I suspect very little testing goes into it.I do appreciate that they will replace it, but you pay a premium for the extended warranty and then you have to live without the ring for yet another week while they post a new one from Bangalore.I enquired about some sort discount on some of their other products as way of compensation but they don't seem to care much about customer satisfaction and gave me a hard "no". I will continue to use and its probably a bit of an unfair review as I do like the ring when it works, but ultimately if I was making the choice between Oura and Ultrahuman again, then I'd go with the Oura.Other features all work nicely, accept the step count massively under estimates, I walk quite a lot each day, typically 10,000 on a smart watch, and I get about 7k at a push on the ring. Battery is good, but the ring does show scratches.Anyway two stars for today, but on other days its a 3.
