I love my new cordless WaterPik. It is so easy to use and makes my teeth feel so sparkly and clean just love the way my mouth feels after I have used it. Don't know why I waited so long to get one!
I needed a portable version of my home waterpic which I could use on my trips. I researched all portable water flosses and found the WaterPic-450 to be the best. I bought one, and have used it for three trip: 1 international & 2 national trips. I have found the WP-450 to be powerful, easy to hold, a significant water reservoir, a multi-user with just one charge, and easy to travel. I am very happy I bought the WP-450.
Our Dentist recommended this product for my husband who is getting abscesses around his implants. Unfortunately he can't stoop over the sink as you should, turn it on and off, fill or empty . But, I'm monitoring the procedure and hopes it will help getting the gum area clean. I guess at 90 we should be happy he has his own teeth. I have a similar WP and get praises from the dental hygienist on how good my gums look (I'm not 90 though).
It is ok but not great like the big home one . It is clumsy and stream is not steady I am a little disappointed but I needed something for travel and therefore it does do some good.
