The IPX7 waterproof rating ensures safe operation in wet environments, such as in the shower. However, users need to ensure the nozzle is firmly inserted to prevent leaks.

While the flosser is easy to use and has a memory function to remember your preferred settings, it is worth noting that the motor, although upgraded for better performance, operates quietly under 55dB, which might be considered a plus for some users. This product comes with 5 replacement heads, a user manual, and a charging cable, making it a comprehensive package for maintaining oral hygiene.

The absence of a charging adapter might be inconvenient for some users, as they will need to use their own 5V adapter.
