Good for kids
Color: Blue+red
A little powerful for my 8 year old at first but after he got the hang of it, he loves using it.

Great for dental appliances
Color: Pink+purple
My daughter has a dental appliance that can get food caught in it. We were told to try a water flosser to get the trapped food out. This has done exactly that. Very happy with it.

Fun new way of flossing.
Color: Blue+red
My 7 year old loves it and it works really well. He’s excited about teeth brushing time again accompanied by water flosser and it can be used in the shower!

Leaks
Color: Blue+red
Water leaks out of the button you press to change out the head so we will be sending back. Other than that it would be perfect, I’m sure it’s just a fluke thing.
