The lamps are unquestionably high quality and fulfill their purpose to see and be seen well, the batteries are not empty after the first tour, but hold long enough. However, under a complete set I verstehhe that I do not need any additional components, which unfortunately is not the case and is visible at first glance. The enclosed charger is a power adapter, which only the front light, which has a corresponding socket, can be loaded. The battery pack from the rear light needs to be strengthened and a separate charger, which I now but in addition need, charged ... annoying.
