The tools make a very good impression, the processing works of very high quality. The nuts are coated with plastic and have also inside a plastic bearing for the bolt / nut. The design of the cassette makes me suspect that they sooner or later give up the ghost. Nevertheless, it makes a relatively good impression in terms of workmanship. There is also a difference for imaging, the cassette is not black and red as shown. Although the entire tool set has its weight, the individual nuts are relatively easy but the alloy. I chose it because I just need the greatest width across flats. All in all I am very satisfied.
