Finally a comb that works! After a week of white vinegar, coconut and oil daily grooming with a mid-lice comb nits mi (my 3rd acquisition), I finally bought the Assy2000. It clearly makes the difference: it hangs well, where with other combs must be the reinforcement of the nails to loosen the nits junk. Nits and lice, even tiny, complete their life miserable bloodthirsty lice in the water bowl / vinegar / essential oil of lavender. After 3 days of additional sessions, we got rid of the disbelievers. The icing on the cake: the nits are visible on the comb as it is metal and it cleans very easily.
