The size of the box came as a bit of a shock although listed on amazon. I just didn't read the dimensions I think it's 6cm by 10cm so I knew straight away that the comprehensive training guide could not be a book. I hoped for a booklet but it's a leaflet. Other than that I like the treat bag and clicker/whistle. I have used the leaflet and trained my 2 puppies to sit and to come when called. If your looking for some very light reading to train your dog to do about 5/6 things then this is the kit for you. I'm going to get a book to supplement it.
