I use the irrigator, which had to be exchanged once before to guarantee due to a charging error, alone. Therefore, the nozzle remains in the handle and is not permanently changed. But within a few months already 3 nozzles in the area of the groove are broken out for the catch and therefore jump after switching out of the holder.
Despite the otherwise satisfactory cleaning I am now disappointed and will try to contact me for this "breaking point" to the manufacturer.
