I wasn't sure that I would like using a waterpik. My dentist suggested that I get one, since I have implants and food could possibly get stuck under the tooth. I've always used dental floss. This waterpik is so much nicer and easier. It can remove anything that might be caught under the implant. I highly recommend this waterpik.
I got this product as a gift to have when traveling. I am a confirmed, dedicated Waterpik user and packed my regular model WF-07W for travel. But when TSA took exception my wife took that as a 'need' to have this model. It works but really isn't comparable to what I use normally. In fact I look at it more as a disappointment as it isn't really that much different in size and I can't make any adjustment. But it is convenient and it works better than any non-Waterpik alternative.
