Very well, too bad there's no French user manual; using it on iPhone doesn't work.

This brush is excellent, arriving in 3 days with Polish for English. It's clearly superior and more practical compared to the Soccas X3. I advise purchasing it!

The product matches its description. Delivery was quick, and the packaging was undamaged. The device appears to be functioning well, at least from my initial assessment. I'm pleased to have a new toothbrush after my previous x3 model stopped working; the seller informed me the warranty had expired, requiring me to purchase a replacement at full price. I hope this one lasts longer.

The product is good, and the cleaning it does is excellent. I connected it to the app initially, so I am currently very happy with it.
