I can not say much negative about this set actually. The detergent is great, the finish is ok even if the application is a bit more difficult. Under no circumstances bring on brake discs! I would still not buy it again because it's just an exaggeration. Which areas should I use the large brush is beyond me, so I could sweep up almost the yard. 2 good brushes with some combination effect would have really passed. Who really needs much hardware does certainly nothing wrong, and the price is also justified. Buy For all other simple Muc-Off Cleaner Cycle Cleaner, a good brush and a spray bottle to take you ehh lying around en masse.
