【良い点】 Xiaomi Smart Band 9は、旧モデルと比べてディスプレイ輝度が強化され、屋外でも格段に見やすくなりました。新たに環境光センサーが搭載され、自動で画面の明るさを調整するため、屋内外問わず視認性が安定し、バッテリーの無駄な消費も抑えられます。 バッテリー持ちは前モデル同様に最大21日間と非常に優秀で、睡眠・心拍数・ストレスなどの健康管理や、150種以上のワークアウト記録、LINEや着信通知機能なども健在。Android・iPhoneどちらでもしっかり使えます。前回いつ充電したのか忘れてしまう程にバッテリーの持ちが良いので、ここが最大のメリットだと感じています。 操作面においては「繊細な挙動と滑らかさ」とまではいかないものの、スワイプやタッチ操作は概ね良好です(動画参照)。 さらにクイックリリース構造によりバンドの交換がより簡単になり、ファッションやシーンに応じたカスタマイズ性が向上しているのも好印象です。 【気になる点】 Smart Band 8と同様、GPSが非搭載であるため、位置情報の記録にはスマートフォンとの連携が必要です。また、通知の詳細カスタマイズにはやや制限があり、全てのアプリ通知に細かく対応できるわけではありません。多機能な分、初期設定がやや複雑で、スマートウォッチ初心者には少し慣れが必要かもしれません。 また、Smart Band 9はサウナなど高音な場所に持ち込むと強勢シャットダウンする仕様に変更されてしまったため、再起動には専用充電ケーブルが必要になる為注意が必要です。一度旅行先でシャットダウンしてしまい、帰宅するまで使用ができない事があったため注意が必要です。 【総評】 Smart Band 9は、旧モデルの利点を引き継ぎながら、視認性・使い勝手・デザイン面をしっかりブラッシュアップしています。GPSが不要で、日常的な健康管理や通知確認を手軽に行いたい人にとっては、引き続き非常にコスパに優れたスマートバンドです。

睡眠ステージのモニタリングをしたくて購入。 程よい大きさで軽いため、就寝中も気になりません。 バッテリー持ちも良く充電も速いのですが、時折、スマホとの同期が外れます。 原因によって対応の仕方が変わるので、ご自身で問題解決できない人だと使用が煩わしく感じるかもしれません。 また、購入時に本体に付属しているリストバンドは外れやすいので、オプションのバンドに交換することをお勧めします。

スマートウォッチを、試しに使ってみたい方に、オススメです。 スマートウォッチはお値段が張るものが多いてすが、手が出しやすい価格設定が嬉しい。 電池持ちも良く、ゴツくないのも良いです。 バンドも着せ替え可能なので、好みのバンドを購入し気分やファッションに合わせて変えられるのも楽しいです。

1年以上使用。相棒。 バッテリーがとにかく持つ。 色んなスマートウォッチを使ってきたけど、充電という行為が少なくなるだけでこんなに快適かと実感する。

夏場 野外で使うと スマートバンド本体が温度上感知して全く使えなくなる。 専用の充電器に一度接続し治さないと使えない 前に使ってたMi Band 5 ではそのような事例は起きなかった。(なんでも外気温と体温両方検知して急激な温度上昇で本体が止まるみたい。) それ以外はとても使い勝手が良い。

スマートウォッチ入門として購入。この価格で睡眠や心拍数のログ、各種通知の確認、150種類以上の運動記録までできるのは驚異的です。バッテリー持ちも良く、頻繁に充電する手間がないのも嬉しいポイント。日常使いには十分すぎる機能が詰まっています。 ただ一つ残念なのが、画面の着せ替え(ウォッチフェイス)のデザインです。公式で200種類以上用意されていますが、全体的にカジュアルなデザインが多く、ビジネスシーンやフォーマルな服装に合わせやすい、洗練されたものが少ないと感じました。 機能面ではほぼ満点ですが、文字盤デザインの選択肢の少なさが少しだけ気になり、星4つとしました。とはいえ、それを差し引いても有り余るほどのコストパフォーマンスを誇る一台です。

Great product
The fact that i can used as a keychain is a better alternative for a pedometer, it’s not accurate but it gives you a peace of mind knowing your estimated steps. I find it better and compact compared to apple watches. I do not use smart watches as my main watch

軽量でかさばらず、寿命も長いにで健康管理に最適。寝ている間も付けているので、睡眠の状態も分かつが、普通以下の睡眠時間で警告が出ている。改善する表示を示してクルルのでありがたい。

I have this band after my Iwatch was broken. I realized I didn’t use the full functionality of it, because the watch screen is too too small to do anything complicated. I also don’t need (don’t want to be interrupted by) all the notifications/functionality like using my phone. Therefore, I decided to focus on what I really need, which is fitness tracking. I tried the other more famous band, which looks great. But the battery life was a big concern to me. It didn’t last one day after I turned on all functionality. It might be defective, since it claims a little longer Battery life than that. Besides, I had to pay for some functions. So I switched to this one, cheaper but with longer battery life. The battery life is really amazing. With all functions on, it can last 10 days or more (I never let it go down to 30%). When I have a short business trip, I don’t need to bring a charger at all. It provides enough fitness tracking. By comparing with my old Iwatch, I found that the Distance is accurate , the steps is a little lower but ok for me. The calories are very different (I heard the calculation is different). But it does provide me the relative information for my day to day fitness activities. I have it on my wrist all the time. Charging is also very fast. I like it very much!

I had the Smart Band 6 previously, and when that one eventually died, I was happy to get the latest one, which was at the time, the Smart Band 9. Mostly I really like it. I keep my phone on silent, so the only feature that I really need is to be notified of incoming calls and texts. Everything else is nice to have, so spending $200, $400 or more for an Apple Watch is overkill when this one is $47 and does what I need. Things I like: - Durability - Water resistant: I accidentally wore it in the shower a few times, and it was fine. - Watch face is not huge like most smart watches. - Color screen with lots of free watch faces. - Syncs fine with iPhone. - Long battery life. - Value, as discussed above. Cons: - One other SUPER useful feature the Smart Band 6 had was that you could use the watch to make your phone beep so you could find it. While this one technically has that feature, there is one critical flaw: If my phone has its ringer off (again, see above - my phone is ALWAYS on silent), then when you use the watch to find the phone, it no longer beeps, it just vibrates. And this is not due to a change on Apple's side since I was using the same phone. - A few of the watch faces are customizable, where you can choose what info you want displayed (steps vs heart rate vs ...). I wish more of them were customizable. Also more watch faces with large print and simple designs for those of us who have bad eyes would be much appreciated. Overall, I 100% recommend this watch. Just verify if it has all the features you need. If so, get it!

My fitbit charge 5 decided to quit on me after 1 pool session so I found this alternative. Let me tell you, I didn't have my hopes high but I was pleasantly surprised the first day I started using the Mi band! First off, the battery life is AMAZING. It has wonderful visuals, apps, and options yet it can last a whole week (or more depending on the settings you choose) compared to the boring, small, and not simple things of the fitbit. For the price you literally can't beat it, I swam with it in the pool and the ocean and the waterproof rating is doing its job! (Shame on the Charge 5 that got water damage and only had it for 6 months) The heart rate sensor is decent, not as perfect as the fitbit but gets the job done. Sleep tracking is pretty good as well for what I use it for. I also get notifications instantly to the watch which is super nice while working to check quickly without having to take my phone out. Overall 10/10 for the price! It has plenty of features and it looks nice too with plenty of watch faces to choose from. The app is also easy to use as well.

Bought this to track steps and workouts and I'm pleasantly surprised! It's excellent quality for the price. Tracks heart rate and sleep pretty well. Battery life is great so far, I've only been using it for approx 2 weeks. Loses a star as it's not as robust as some of my old fitness bands, I knocked my hand into a door and there is a minor scratch on the screen. I know from experience others held up better with minor bumps and knocks. Although there are many functional and pretty watch faces to choose from in the app, I would like some more customisation with the watch faces.
