Epilady nail clipper and file set - Case of 24

How fast it is? It is faster than the other known brands like Braun, Philip or Remington?

Does this have dual voltage for international travel?

Will this work on the armpits and bikini area and for the men that gross back hair?

Can this replace the waxing of legs and facial hairs I have done every 4-6 weeks; in other words, does it do the same clean job as waxing?
