Dentist recommended water flosser to me. Is this any good?

Anonymous
I have this high-end-ish dentist, so I guess you can consider him part sales agent, as the villa he works in has all kinds of products on display.
He recommended me a water flosser. My questions is: how good is this thing?
(I have a brace, so it is harder for me to brush in certain areas)
