Easy to use
Now sure what they’re talking about warmth.  I love this flosser.  It has different setting, I use soft which is still pretty strong.  The water pulsates through and you have to be careful with how wide your mouth is open or water gets everywhere.  Definitely makes me want to use it.  Only drawback is where the buttons are placed, I’ve accidentally turned it on a few times and water sprayed all over the place.  The water tank holds enough for two uses, but the charger lasts forever.
