These tools of any brand with the spiral rubber tip at the end not only do not clean the ears, but make them worse. They mix the wax in such a way that completely blocks the ear canal, after using them you hear nothing and need an ENT or ear drops for days to restore hearing. They can also injure the eardrum and the ear canal. We should never use them under any circumstances. Generally, we should never put anything inside our ears, not even cotton swabs or even the in-ear (buds) music headphones that we all use are dangerous, let alone such sticks that reach the eardrum.
