Does the job, performs as expected
For a portable cordless Flosser, this model is pretty impressive. I find it offers a gentle yet sufficient force on the low setting, while medium and high settings are more than plentiful force. The quad nozzle is my favorite, the regular nozzle seems more targeted for a more forceful flush. I have a small mouth, this fits inside easily and I find it easy to use. The water container is small and often needs two fills for a complete job. Only concern is the plug, it seals fine for now. Hope the seal doesn’t weaken over time. For the price and ease of convenience, small footprint and mobility, I like it. It does the job! Spouse has one too 👍👍

すっきり感を実感できる！持ち運びできるのも◎
歯間の汚れが以前から気になっていました。コードレスなので、いつでもどこでも使えるところがとても便利です。 X型水流の力強さにびっくり！しかも、とても心地よい強さです。短時間で汚れをしっかり落としてくれるので、仕上がりが本当にすっきり。クリーンモードとディープクリーンモードがあり、選べるのも気に入りました。歯間の移動ガイドがあり、初心者でもスムーズに使えます。タンク部分を取り外して洗えるのも、清潔に保てていいと思いました。電動歯ブラシと一緒に使用していますが、ケアで歯の健康を保っていきたいです。

今までにない強力な歯の汚れ落とし
歯の隙間に水が勢いよく入り、今までに無い感触の歯磨きでした。 歯の掃除に毎月歯科医院に通っていますが、その時のスッキリ感が同じように味わえました。 歯の間に詰まっていた食べかすも 水と一緒に洗い出され歯垢も落としてくれたように思いました。
