Bought this product about 4 weeks before the theory test, cause I realised I wouldn't be able to pass the hazard perception part without practising. I had official bundle
The Official DSA Complete Learner Driver Pack: 2008/09 Edition: Valid for Tests Taken from 1 September 2008 and had no problem with it preparing to multiple choice part, but DVD about hazard perception was not particularly impressive. It is a good introduction to hazard perception, but it is only an introduction and does not improve your hazard perception skills.
This software program on the other hand explains you everything in more details and allows to practice on numerous amounts of clips. I liked the way it shows and explains what hazards were, and when it started to develop. A very nice intuitive interface for the most parts is provided. The only thing is that the back button in the left-top part of the screen is not obvious in the beginning, but later I found it to be very convenient.
There are explanatory videos about the test and introduction to different particular type of hazards you should be looking for.
There are 42 complete tests with 14 clips in each. And all this clips are different. I have to mention, that they filmed on about 30 different locations, so you will see different clips from the same places. Though it might be a plus, because the situations and hazards can be absolutely different and it teaches you to look for all types of hazards, despite location being the same. The quality of the clips are good. Don't expect a crystal clear or HD quality, after all they used just a web cam stuck on a car, though it was clearly a very good webcam.
I had time to pass only about 22 tests, but in them I did not have a single clip shot at night. I had one clip featuring night driving during my "real" exam.
Overall I managed to learn how to pass the test, but in the same time I developed scanning and anticipating skills. The clips also are very good illustrations how professional drivers behave in different situations.
I passed my test at the first attempt, scoring 59 out of 75. Knowing traffic signs and highway code definitely helps though :).
Overall I am pleased with this product.
P.S.
As a side note, I would recommend to enable option to play videos in a full screen mode - easier to see hazards and it is the way they will be played at an actual exam.
