Then write down what I tell you because once the product is tested it will not be returned or exchanged by your dealer (local) and yes as hygiene products.
THIS PRODUCT HAS NO POWER !!!!! I STRESSES that because it is the main interest of a water pick. My product is down because the change in speed is felt even at 5 but the jet has very, very little efficiency! Sensitive gums I really did not have any problems, to tell you the little delivered power.
Only nice thing Airstream position with water pleasant feeling.
So I will try to contact the customer service and will direct me to a WATERPIK device.
To note; I have nothing against this mark, but this product and really a gadget! You have been warned!
