Bought this product soon after I had orthodontic work. It cleans far better than brushing alone and string flossing is no longer practical for me. This model (WP-450) has two speeds but I only use the higher setting because it seems to clean better. I like that it has a rechargeable battery which is good for a few cleanings. The reservoir holds enough water for about 45 seconds of cleaning so I usually end up refilling it several times during a single cleaning session. But....I still like the convenience of being able to easily put it away in a cabinet when I am done. Bottom line: I am pleased with this product in spite of the fact that it is made in (you know where). Final note: I rated this product as good (4 stars), but I feel that it should be good+. Maybe 4.4 out of 5 stars.
