Is it good for braces?

Yes. The multiple modes and included orthodontic-friendly nozzles let you clean around brackets and wires. Start on a low mode and work up.

How long does the battery last?

A full charge typically covers several days of once- or twice-daily use. Charging is by USB cable, so a phone charger works.

Can I use it in the shower?

Yes. The IPX7 waterproof rating covers shower use and rinsing the body under the tap. Do not submerge it for long periods.

What comes in the box?

The flosser, several interchangeable nozzle tips, a toothbrush head, a tongue cleaner and a USB charging cable.

How is it different from a countertop flosser?

It runs on a battery with no cord to the outlet and has a smaller tank, so it travels better but needs refilling more often than a large countertop unit.

How often should I replace the nozzles?

Replace tips every three to six months, or sooner if they look worn, the same guidance as most water flossers.
