I love this, it works so well.
I have this hooked up to the sink.  I like controlling the water pressure at the handles as well as on the attachment. It doesn't take much water to create strong pressure.  I also like that I don't have a reservoir to fill and that it's not noisy.  It works great.  I would like another one in the shower as well if it can be made to fit my pipes.  I don't use the colorful plastic washers on the tooth brushes at this time because it oddly is sealed better with no leaks with them off.
