This set is not only great because it provides everything you need to clean your bike, but also gives you a place to put it all (the tool box). The cleaning products are high quality and work! They also have instructions on each of the cleaners and brushes to let you know how they are used. The spray on wax leaves my bike very shiny to the point you can see your reflection. I've ridden on gravel trails and this cleaning kit gets my bike looking like new every time I use it.
The Muc-Off product line does an excellent job - each product tells you what it is best used for and they do that use well. The bike specific products (IMO) tend to be a little more expensive than other bike cleaning product I've used, but I have to say that I do believe I use less because they are so effective.
