Review on Enhanced Canine-Friendly Bark Notes Patch for Collar or Leash by Stacey Williams

First of all, if you have a large dog or want people to be able to read the patch remotely, don't buy this. It's tiny, which is fine for my purposes, but probably not for most people. Also, the opening is huge. I don't understand why they made it so deep. A leash or collar strap may be 1 inch wide, but dog collar/harness straps are slightly thicker than a piece of cardboard. The opening of this pad fits 1" wide belts (probably up to 1.5"), but this one is also 1" deep so it just slides down and isn't snug. I don't know why they made it 1" wide and 1" deep. No collar, harness or lanyard measures 1" x 1" which would make them square instead of flat.
