Reviews
“Satisfying toothbrush: I'm happy with it. The light turns on when I apply too much pressure, which helps me be careful. However, since it's located at the bottom, I sometimes miss it.”
“Leaves teeth smooth: This model leaves my teeth smoother than the higher-end models. The battery life is sufficient, and I appreciate that I can simply turn it on to get ultrasonic vibrations without needing multiple modes. I also own the Diamond Clean, but switching modes is cumbersome, and the battery has weakened over time, making repairs difficult. That's why I decided to purchase this model. I plan to use it regularly.”
“Decent deal when on sale: Not a bad deal but the handle is slippery.”

“Highly recommended: I previously used a dental clinic's exclusive product, but this time I decided to try this one. I purchased the basic model since I don't need any extra features, and it has worked perfectly. The brushing strength is just right for me, and I appreciate that it automatically turns off after 2 minutes.”
“コンパクトで使いやすいコンパクトで使いやすい: 頂き物のBRUSHMOの電動歯ブラシをずっと使っていたのですが、PHILIPSとかpanasonicみたいな有名メーカーだと違いがあるのか気になって購入してみました決め手になったのはPHILIPSの場合は「値段が高くなると色々な機能が付くけど基本性能は変わらない」というところです歯垢除去能力も「ブラシの種類次第」っぽいので（メチャ高いやつは知らんけど）、本体は安いやつ買っていいブラシ買おうと思いましたBRUSHMOも基本モードしか使っていませんし、遥か昔にBraunを使っていたときも基本モードしか使っていませんでした3か月に一度歯医者さんいってるので基本モードだけでいいです1個下の2100シリーズにしなかったのは「強さのお知らせ」を一度使ってみたかったからですでも相当強く押し付けないと鳴らないみたいで自分には必要なかったです2階の洗面台用に2100シリーズを買おうかと検討中です高い機種は分かりませんが、BRUSHMOから乗換えて良かったのはまずコンパクトで持ちやすいことちょっとの差なんですけどだいぶ使いやすいですなので小ささを重視して高い製品を買うのはアリだと思いますもうひとつ良かったのは振動が細かくて狙ったポイントに当たってくれるところです改めてBRUSHMOを使うと動きが大きくて歯と歯茎の間をピンポイントで狙えてない感じがします（暴れちゃう）個人的には大正解の買い物で、もっと早く買えばよかったなと思いますブラシはとりあえず付属のものを使いましたが、もう少しランクの上のものや、BRUSHMOの互換品などもちょっと試してみて、コスパと磨きやすさで自分にあったものを探してみたいと思います”
“Can be polished beautifully: There is no doubt that it is a good product, and it is easy to use.”
“Significantly reduces plaque during dental check-ups, perfect entry-level model for switching from manual brushing: 【Reason for Purchase】 I was advised to introduce an electric toothbrush after being pointed out for plaque during a dental check-up. I was torn between Oral-B and Sonicare, but chose Sonicare based on the dental hygienist's advice that sonic models are gentler on the gums. I compared it with higher models but opted for the entry-level 3100 series since it was my first electric toothbrush. 【Difference from Manual Brushing】 Honestly, I felt the difference from the first day. The sonic vibrations felt a bit ticklish at first, but I got used to it in 2-3 days. Thanks to the 2-minute timer and the 30-second interval vibration change, I developed a habit of brushing evenly on all sides. After using it for a month, my dentist praised me for the”
“Cleans well: The vibrations feel weaker than the previous model, but it cleans nicely. I'm also concerned about durability. By the way, the previous model broke down after 3 years.”
“I want to use it for a long time: I used to use a Panasonic electric toothbrush, but I was concerned about toothpaste flying everywhere. This one cleans well, and the price was affordable, so I'm very satisfied.”
“It's generally good: At first, it feels a bit too strong, but you get used to it and it works fine. The reason for 4 stars is that when you place it on the stand close to a full charge, it makes a beeping sound that loops endlessly.”
“エントリーモデルでもしっかり歯垢は落ちる: 7年くらい前に買ったフィリップスの電動歯ブラシを使い続けていたが、何となく最近歯垢の落ちが悪いなぁと感じてエントリーモデルを購入。結論から言うとこいつで十分歯がツルツルになります。高いものと比べると色々モードが付いてないが、前のフィリップスの電動歯ブラシも結局一つのモードしか使ってなかった。ならばシンプルなこちらでも十分だな、と良い選択をしたと思った。前よりも取っ手がスリムになって、表面もサラサラしている。が、手の大きな自分にはちと持ち辛い。そしてサラサラ過ぎると手が滑る感覚がある。ゴムのグリップが付いてれば尚良しだな、と思った。けれど、この低価格で歯がツルツルになる洗浄力は星5つ与えて良し。電動歯ブラシ初心者、試してみたい、という人にもオススメです。”

“Easy to use: This is the best choice. It's affordable and lasts for several years, so I recommend it. If the buttons wear out, it's time to replace it.”
“Pretty good: I had been using a Doltz for many years, but I forgot it at my parents' house and had to buy this one! It's a budget-friendly model, but I think this one is newer, simpler, and has better basic performance! You can also use compatible replacement toothbrush heads!”
“The charging cable is USB. This is a repeat purchase, and there are no particular issues. However, this time the charging is via USB, and I would have preferred it to be from a regular outlet.”
“２年保証がついており保証書がWEB登録できる: スイッチ部分の故障のため買い替えましたが、数年で製品が改良され磨き上がりがとても良くなっていました。２年の保証期間がありアプリで領収書を保管できるので紙での保管から解放されとても気が楽で嬉しいです。登録もシンプルで洗練されていてスマートなブランドな印象です。以前と品番が違うのですが充電器は互換性があり、本体だけ購入できたらエコでいいなと思いました。良い品と巡り会えて日々の歯磨きが少し楽しくなりました。”

“Just, just disappointing: I purchased an electric toothbrush (Sonicare) a week ago, but after the battery ran out and I tried to charge it, the charging light didn't turn on at all, and it won't power on. It seems I can't return or exchange it, and I'm extremely disappointed.”
