May I have your recommendations for buying a TASER, please?

How old is she and what state is she in? Actually, don't tell me what state she's in. But you or she will need to research the applicable state's laws regarding personal defense.

I don't believe that the police style line and dart tasers are legal for the general public, so anything that would even be potentially available would be the direct contact type.

I don't know enough about those to offer any useful advice or product recommendations.

Have the local police been contacted about this? Is there any legal recourse that she can take? Protection from Abuse orders often don't work ... but if she has one and he violates it and she uses some means of self defense, no matter what it might be, she may have better standing in court if she gets charged.
