This is used by the army and i have used this when travelling throughout the world, in my opinion this is the best repellent out today, i have never found this repellent on sale in any shops as it was made and designed for the M.O.D.  you now have 2 options get bitten or buy this and lets those mosquito's feed on someone else.
