The video features a person building and reviewing the Lego Technic Liebherr R 9800 Excavator, which is the most expensive Lego Technic set ever made, with 2883 pieces. The model is based on a real-life crane and features 6 large motors, a lifting capacity of 3,000 tons, and a phone app to control its movements. The reviewer finds the model's price to be unjustified, comparing it to another excavator model they built earlier, which had more parts and 7 engines but was not as expensive. The reviewer demonstrates the model's features, including its movement and lifting capacity, and tests its weight limit, finding it to be around 1.5 kilos.
