I have had my Waterpik-100 almost a month. I enjoy the fresh feeling after I finish flossing. The array of tips is a wonderful feature. I got the navy color and love it. Minor point - I wish the latch on the tip container/lid was more secure. It tends to open when I lift to fill with water.
I am extremely pleased with my new water pick. I like the different cleaning tips for bridges/braces, the fine point nozzle and the (2) brush styles for cleaning along the gum line. Great product and I highly recommend.
Overall, my second water pic, after over 10 years of use from my last one, worked as well as expected. I enjoy the improved on/off function on the wand. The only thing I would recommend me users if to run at least 3 full reservoirs of cold water through the supply before use as the taste of plastic is strong when you first use it.
