These are excellent tracks and the detail is great as well. However, they do take a long time to assemble. Each track link consists of 5 parts: the track, a connecting link and 3 link pins. The supplied wire is run through the holes which must be drilled out to remove grease and metal flash with a .5mm pin vise bit. It also comes with 2 18-tooth drive sprockets. So this is meant for 'initial production' Tiger & Jagdtigers, since the 'early production' had 1 connecting link and no pins also they had the common 9 tooth drive sprocket so you'll have to decide on which parts to use based on the vehicle you model. Overall the kit is good but the tracks are very time consuming to assemble so I wouldn't recommend it to those who like ease of assembly.
