A high-pressure hydrojet, slow reflexes and an inexperienced user was as effective on the mirror as it was on the gums. This does take time to get used to so it would be wise to use the low-pressure tip initially. The amount of force and positioning of the on/off buttons which are slightly awkward can make for an adventure. Nevertheless, this is an excellent product with pulsating pressure, effectively cleansing the gums reducing the chances of developing gingivitis and removing the bacteria in a superior manner. It is quite compact with an all in one hand held water container attached to the waterpik. The rechargeable feature eliminating the cord is an added bonus. It is well worth the positive outcome you will receive at your next dental visit.
