The bicycle trailer was easy to assemble, but was immediately rebuilt by us in a jogger-car (have the necessary equipment for this purpose to be ordered). The car was well received by our dogs and a "test-beds" was still carried out on the day of installation. Overall, the car is quite bulky and I recommend him to use only on asphalt / solid surface, therefore could not be awarded full marks. For our purposes, (we have an old dog, but also on long walks or jogging tours "necessarily want to") the car is well suited and we and our dog are very happy with the car.
