Query: Works well kind of hard to put on take off.

I like how it works. My dog has quit pulling on me constantly. It is great for the price. The only problem is taking it apart to put around the dogs next. It snaps off between the teeth and it's very east to do. It's not that bad though.Also it came in just 2 days but I discovered it was shipped from about 150 miles from my house so that was nice.
