Review (5/5): Better than my old one
I can't use dental floss. There are 4 modes of this water flosser. I recommend the gentle mode for beginners. Because flossing makes my gums worse and bleeds more. But I've been using it for weeks and I'm amazed at how well it cleans. It's better than the older model, it's more powerful, it doesn't take up too much space, and you can take it with you when you travel.
