I really like this product. It does as it says. Good diverse tips. The power settings really give you good choices. I would have given this 5 stars except for the fact it is very loud. However that does not affect how it functions.
When my son had his braces put on it was really hard for him to get his teeth "really clean", our DDS suggested a WP-100 as they have the same style in their office. The dental hygienist showed him all of the great things he could do to clean his teeth better with having braces on. I would ABSOLUTELY RECOMMEND this to anyone who has braces. I also use it myself and love how clean my teeth and ,mouth feel after. 5 STARS all the way!!
