How many pressure settings does the Coslus EX1 have?

It has 12 pressure settings, so you can start low for sensitive gums and increase the jet for tougher debris.

How many nozzles come in the box?

Five irrigator nozzles are included, which lets several people in a household each use their own.

It is a cordless electric flosser, so it runs on a rechargeable battery rather than a cord to the wall.

The lowest of the 12 settings is gentle enough to start with, and you can raise the pressure as your gums adjust.

It offers more pressure steps and more included nozzles, but Waterpik has a longer track record and easier access to replacement parts.

A water flosser cleans between teeth and around braces, but many dentists still suggest string floss for tight contacts.
