I was urged to get a Waterpark, by my Dental Hygienist. I have been amazed at how well it cleans out the food between my teeth. It is much easier to clean & massage my gums with Waterpik.
Since this is the first water pik that I've used, it's hard to provide a good critique. I can say, be careful when removing the pik from your mouth and it's still on; I squirted myself in the eye & nose, Ugh! It seems relatively easy to handle but I wish it held more liquid.
Its smaller size causes it to run out of water quickly, but didn`t prefer to pay more for a larger model. Fulfills the reason for having this kind of product.
