Hi,
I rec'd an email the other day suggesting the use of wasp spray as it is stronger than pepper spray and doesn't require you to be close to the assaulter as you can spray from several (like 20 ft away). Pepper spray and stun guns require the person to be very close. I say treat em like a bug!!!
It works more like the shotgun effect...you don't have to be so exact, either.
Much less expensive, too. Ultimately, you need to use what you feel most comfortable with and especially in a stress situation. Have a safe trip. K.
