  1. If you are going to create a video please use spell check. Putting has two ts.
    Which is spelled which and not witch
    repellent has two lls and
    duration is spelled like this.
    This adds more credibility to your video, which by the way, I can hear and I’m not a teen.

  2. I’m 67 yrs. old and my husband is 73 yrs. old and we both heard it all the way through the video, till it said the dog stopped barking!

    What kind of ruse is this?
