今まで使ってた第三世代がバッテリー持ちが怪しくなってきたので第五世代を待つか第四世代にするかずっと悩んでいました。 でもやっぱりバッテリーもただ不安を抱えて使い続けるよりも買い替えを決断しました。 結果は替えて大正解でした。ちょうど価格もセールで下がっていたので少しばかりお得に買えました。 なんといってもバッテリー持ちがいい。個体差はあると思いますが私の場合はGPSオン、spo2常時オン、その他使える機能はほとんど有効にしていますが100%から20%になるまで8日待ちました。今までは持って3日だったのでそれだけでも良かったのですがデザインが変わったことによりつけていても違和感を感じません。 サイズ的にはほぼ変わっていないと思いますが内側のセンサーの突起がなくなったのとリング自体の形が真円のみになったので中指にも違和感は出ていません。つけている指は左手人差し指です。気をつける点と言えばもしもいま第三世代を持っていて買い換える時にそのままのサイズで移行したくなりますがセンサーの突起がなくなった分やはり少しだけ緩めです。私は元々最初買った時よりも指が太くなっていたので第三世代が結構きつめだったのでそのままのサイズでジャストでした。 不安がある時はやはりサイズテスターを買って合わせた方がいいと思います。 最近はいろんなメーカーから指輪タイプのデバイスが出ていますが、Oura Ringは今までの積み重ねがあるのでアプリもとても見やすいしわかりやすいと思います。欠点はそのアプリがサブスクでないとほとんどの機能を使うことができない事ですがそれを補っても満足はしています。 長々とわかりづらいレビューになってしまいましたが少なくとも買った後悔はしないと思います。

Works great
Thought it would be more chunky but it’s not. Accurately tracks my workout heart rate and sleep

毎月、999円費用がかかるのとスマホアプリの内容が外国語でわからないので一週間程度っ試して返品した。 返品手数料というのが25000円引かれていた。指輪で健康指標がわかると思い気安く手を出したら損した。

事前にサイズキットを購入して1,2日候補となる指でつけて生活することはマストです。 Ouraリングそのものはデータが好きな人間にとって最高のツールです。 結構厚みもありますが、日常生活で邪魔に感じることはほとんどなく日常の一部になっています。

You'll need to subscribe the app (pay regularly), to have full function support.
Size is accurate. However it's thicker than I imagined. Battery life is good, recharge ~5 days.

見た目はゴツめなリング 軽いしジムでトレーニングする際も邪魔にはならない ただアクティビティの感知が弱めで、筋トレは手動で計測開始した方が無難 スマートウォッチと同時に着用すると、1日の消費カロリーが300kcalほど多く出ることがある。

購入してから2ヶ月でバッテリーが1日持たない。改善の方法はありますか? 交換可能ですか?

Ich suchte eine Alternative zur Sportuhr / Smartwatch und wurde fündig. Der Ring macht nicht nur optisch etwas her, sondern liefert einem auch Daten über die eigene Gesundheit. Er ist ein guter Allrounder und macht einiges sichtbar, was man im Alltag doch gerne übergeht. Mit Hilfe des Ringes achte ich nun mehr auf Bewegung und Ruhezeiten. Die Auswertungen sind zudem hochinteressant. Ich kann den Ring jedem empfehlen der auf der Suche nach einem Gerät ist, welches den Fokus auf die Beobachtung der Gesundheit legt. Sollte der Schwerpunkt eher auf dem Sport liegen, würde ich zu einer Smartwatch tendieren.

I don't like wearing wrist watches, so having a smart ring is PERFECT for me! I love how durable it is, it's easy to clean, and the app that comes with it is GREAT! The tracking on this thing is flawless and it uses light sensors to track my vitals, so it doesn't even feel like a smart device, just a regular ring! It also charges very quickly, so if I'm using the bathroom or taking a shower at home, I just pop it on the charger for 10-15 minutes and it's good for a few days! I only do it daily just to establish a good routine, and I have forgotten before and let the battery get low, but still haven't had the power die on me yet! I can see it being an issue for lifting weights since it's coated in stainless still and a little bulky, but otherwise very comfortable for other forms of exercise! I can also see it being a problem because of the red and green light sensors at night, it might be disruptive to light sleepers in a dark room, but I just keep my hands under my blankets or pillows, and I sleep just fine! It doesn't light up all the time, just periodically throughout the night. If the tiny lights at night might bother you, you can probably put a thick sock or a glove over your hand at night to block the light. I'm personally not inconvenienced by it at night, and I like that I can't feel anything when it checks my vitals (heart rate, blood oxygen, temperature, just to name a few). I wound up subscribing to the app anually because I really liked how easy it was to set up and how thorough its analysis was for my overall health. UPDATE: Recently I noticed the ring was draining too fast between charges and I actually needed to charge it everyday! I reached out to customer service via the app, they asked a few questions, and shipped me another one immediately! It was refurbished, not brand new, but it works like new and I would never have known the difference if they didn't tell me! I keep the old one as a backup just in case since they said I don't need to send it back. I basically haven't stopped wearing the Oura ring since I put it on, and I've used it on long walks, swimming (fully submerged in water), and for general daily activities and it works great! I wash it with soap and water when I wash my hands and take it off to give it an.wxtra good wipe down before popping it on the charger or putting it back on!

Awesome product. Perfection in everything. Does not throw numbers and data and interpretations at you immediately. Comfortable to wear. Just make sure you have tried the sizing kit before hand for atleast 4 to 6 hours if not 24 hours. I am getting a battery life of 5 days plus.

I have been using it for the past 4 months and its very accurate, is not bulky and the battery lasts around 5 days. The key metrics are very useful and it allows me to see how alcohol, a bad sleep or extra caffeine can affect my body.
