Seems to do a good job so far. The water amount and time for one use before refilling is better than I thought it would be. A bit "clumsy" when trying to use on lower gums behind teeth but workable.
I use my new waterpik in the morning and pm when I brush my teeth. My teeth feel so much fresher! The unit is fun and easy to use. One of the best purchases I have made!
This beats flossing. Try flossing and then use waterpik and you will be amazed at all the food particles it removes. I have adult braces and it really helps cause flossing around braces is very time consuming. I do have a recommendation to put a light on the unit so you can tell it's been fully charged.
I purchased this one about 2 months ago to replace a previous one. And, I still do not see an indicator to tell me that the unit is charged. You are very quick to tell us that the unit is for the trash can as soon as the battery is gone (whether that is 1 or 5 years). If you installed an indicator for the charging of the battery then a person would know when the unit needed charging. Please consider this aspect on future models.
I like this model since it has a tab that I use to open the water container and dry it out completely which is so important as it gets rid of the moisture.
