The Waterpik is priced very fairly. The machine is powerful and does a thorough cleaning and is easy to clean. Far superior to Sonic flosser. I had to return 2 sonic flosser in 3 months total due to total malfunction.
I am very happy with the Waterpik ® WP-100. From the pulsing level 1 to pulsing level 2, the unit is almost too strong. Pulsing level 1 is weak and pulsing level 2 is almost painful. Please look into this.
my daughter loves her and she has been telling me to get one for a while. I finely got one and I love it. I thru my floss out, no more hanging up on my teeth. so easy to use. just follow the directions.
