I probably need to get version 3. I bought 5 of version 1 (back in 2013 I think) not long after they came out. I gave them to my son in laws for Christmas presents. I still use my version 1 but I do have to get close for it to be effective!
I have an "inside" dog that is a "peacenik"! Every time I 'c o c k' the Bug-a-Salt, even if the dog is two rooms away, she hears it and comes barking at me! No, I don't dare shoot my dog! (Sorry about the spacing above, the forum profanity filter blocked the original without the spaces.)
