These targets are recommended at this price. Nevertheless, it should be noted that one hardly recognizes anything after 5 meters. After 10 meters it is even more problematic. While it is possible to hit the target at that distance, but more than Einschießscheiben they are not for me. With a suitable backstop shots with a CO2 are - gun dangerous very good, but without goggles because the force permits a loose ball through the target well. But that depends on the bullet trap. To conclude that the discs are okay and sufficient for hobby shooters. Possibly you can also at targets in the format 17 x 17 switch.
