Laifen

The brush does a great job of cleaning teeth. High speed action is soft but effective. Mouth feels good. The app is fine. I don’t understand what issues are. Note that to turn on brush you must hold power button for at least 5 secs when it is stored in travel mode - prevents accidental triggering.

I’m using the Laifen toothbrush and really enjoy the experience. However, I strongly suggest adding support for Apple Health integration to sync brushing time/records. This would make it easier to manage all health data in one place, and it would also keep Laifen competitive with other brands like Philips and Oral-B. Hope the team can consider this in future updates. Thank you!

The toothbrush connected quickly and all of the changes made in the app reflect super fast in the brush. I’m not sure about the other low scoring reviews to be honest. I haven’t had issues like they’ve described. For reference you can use the toothbrush completely independent from the app (minus a couple features). I didn’t download it for a couple weeks and used the brush, no problem.
