I already have an electric toothbrush, an Oral-B, so I'm comparing the toothbrush to that. The head on this is A LOT larger than the head on the Oral-B, so I found myself hitting my teeth with the body of the toothbrush head - very unpleasant sensation and loud buzzing. The multiple modes was an interesting feature. Wireless charging pad for the toothbrush worked very well. The reservoir for the water flosser was easy to fill and put on the machine, which was really good, because the water got used up much faster than I expected. I also started bleeding from the gums when I used it - user error/wrong pressure setting? It comes with multiple types of head for the water flosser, and, a really cool feature it has is that your flosser heads you aren't currently using, stores on the underside of the lid of the reservoir. (Downside, this will probably introduce a lot of germs into what should be a clean environment, once you have used those attachments. I foresee some possible mold problems...) Also, the toothbrush heads come with clear plastic covers to put over the bristles of the toothbrush when not in use. If you don't already have an electric toothbrush, this could be a good combo unit for you.
