I really like the unit, it functions very well, everything you need to start using it is in the box. The only 2 things that prevented me giving the unit a 5 star rating, is the hose, and the lid. I personally find the hose a little short and I fear kinking the hose due to some of the angles needed to clean all teeth. I also find the lid isn’t very functional, it has to be removed to fill and empty the rank. An alternative design might be a hinges lid with a covered pour/ filling spout. But over all the unit functions very well, and I am happy with the purchase.
I'm a first time user. Was recommended by my dentist because flossing is very difficult. Very impressed, it works as advertised and exceeded my expectations.
Works excellent and does exactly what it is supposed to do, you put the temperature of the water you want in and the water tank size is perfect for the job
