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
