I have two irrigators W150 and Nano 310. They work very well and fit perfectly. With this product, as with others I've purchased, I've seen a few negative reviews about not being compatible with certain models or the floss turning on when the unit is turned on. I had no problems with that. **Again I will say, as in my previous review, people should CHECK the models, most of the negative reviews on this product are written by people who have INDIVIDUAL WATER MATERIALS (the ones that look like an electric toothbrush).
