Cleans gums and interdental spaces very well.
It does the job, just noisy which my previous better quality Waterpik was not... that said, I love that the cord from the pik to the water tank has looser coils than my old one... the hose cracked just below the pic and I had never done anything but carefully loop it as it fell into place.
Adjustable flow is important to me to clean the interdental spaces as well as on the gumline.
Glad Waterpik recommends emptying the tank after ever use, guidance missing in my previous one.
One test I did was to brush first, then floss, totally undoing any thought that brushing would get everything foody out of my mouth... the Waterpik still flushed particulate matter out and down the drain, including a couple of sizable pieces too... so Waterpik first, Braun second for best results.
