For a fair review lets see what i think a year later. This product i am using was already replaced under the one year warranty.. The initial product was NOT reliable & didn't last past the initial one year....
I bought this product 3 months ago and have used it 3 times. I found it bulky and difficult to use. Too hard to keep water in my mouth. Too much pressure on my gums. It might be good for others, but I will stick to my toothbrush and floss.
I love this model by results. My teeth and gums feel much better after continuous use. However, it is sold as travel ready and that is not really the case. The reservoir will leak. The tip will break if not removed. That is my only problem with this model.
