Review: 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。
