time delivery, product conformity, sound packages. For this model I replace a very old family Waterpik who had more pressure; my reservations about the WP. 100: I find the pressure up just enough, it seems that the old models I had in time (the third) were more powerful than this one; the other reservation concerns the storage of accessories on the cover, much less practice than in the family model; White would have been more discreet than this electric blue ..the choice was made so the power of pressure for me. It's 27 years since I use a Waterpik, I could not live without it; for me, essential accessory to good dental hygiene, whatever the state of the dentition. Lili
