Giving it a four star because I believe there could always be some improvements made. I've had it for close to a month now, and enjoy using it everyday. Toothbrush is nice: brush head gets into tight places and does a good job. Although some reviewers say it can go for two weeks on one charge, I am only able to get about 6 days brushing twice a day for about 2 to 3 minutes each cleaning. The flosser is my favorite part. I have food stuck between my teeth all the time, (specially meat, veggies and popcorn which I love), and constantly need to floss which would cause my gum to get irritated. No gum irritation since I've been using this baby. It's so easy to use and my teeth and gum feel so clean, I am now using this water flosser two to three times a day when I am home. It does spray water everywhere, so I have to lower my head in the sink which means I can't look in the mirror when using it, but I can see the food particles caught in my teeth going down the drain; yuck, :). All in all, I wish I had bought this years ago. I've been telling all my friends about it.
I stated using the six weeks ago. I had no idea that I had so much left over in my mouth after brushing. The water pic really works it got all the left over out of my teeth
