FWIW I am an OC instructor in addition to firearms. Stun guns, pepper ball guns, etc are well-intentioned toys that don't work in the real world.
I'll offer you this as a fellow Ag: if you can persuade your daughter to make the drive 20-30m north to Hutto, I will give her a free lesson on proper tactics and use of pepper spray and give her a new POM OC cannister, FREE.
Also, good on you for giving a lesson on pepper spray. There is a right way and a wrong way to do it.
