Works well, until the nozzle snaps [SEP] I was happy with this product for the first two weeks I had it, but unfortunately, it fell from the counter of my bathroom, which caused the nozzle to snap. Because the construction of this piece relies on "twisting" to replace/remove the nozzle, it was impossible to "twist" the snapped fragment out of the terminal, which rendered my flosser useless. The other components work well, but unfortunately, this is a major design flaw. I will not buy this model again, and instead, I will opt for a more expensive model with a better mechanism for removing/attaching the nozzle because it is more expensive (and wasteful) to have to replace the entire device than to replace just one component
