Works as advertised, but confusing buttons

It works well, since my dogs neck is rather small it gets loose quickly and ends up activating when it is clipped on and when she is walking around, or scratching her neck. It was confusing to figure out the settings at first, but it's worked very well so far. It has been 2 days using the collar and there is a significant difference in how much she barks and whines when alone.
