I like the ability to use this in the shower (I have the cordless model); makes it much easier and no worries about splashing. Very efficient in cleaning between my teeth!
I purchased this portable version to replace the larger "tub model" I used to have (lost it in a housefire). Because of limited counterspace, this portable version is easy to to keep charged, and doesn't take up any space on my sink countertop. I only need to fill it up twice with warm water during each use -- it is not meant to hold the amount of water the "tub sized" model holds ,and I am fine with that. The Waterpik does a great job of flushing my gums and between my teeth; I use it after brushing with toothpaste.
I bought this at the beginning of June and I’m not real crazy about it. But just because I don’t like it doesn’t mean that someone else won’t like it. The price was good. And it’s easy to use but I just don’t like it.
