Hallo friends few days ago I bought a nova trimmer thats nova1047 ( blue) . Company says that it has .5mm bleade but it realy has 1mm bleade which didnt give you a sharp seaving experiences .also its battery power is so poor that runs only 10-15 mins properly .its take much time to fully charged it around 10 hours .and its bleade is not a stalenesssteal it is normal blead so I recommended you not to buy that product .thank you
