I got this because I wanted to have something for my dog to be able to drink fresh water all day instead of having to constantly change his water. Directions seemed simple to put the product together. All parts was included according to the directions. But it took me longer than expected to finally get it to work like it should. I even had my son come to my house and try it for me. I don’t know what went wrong the first few times but it wasn’t working as I expected it to according to the description. But eventually it worked and now my dog has fresh water on going.
