I can recommend the disc with a clear conscience. Function and versatility are top! Only the impact of the arrows must be assessed as "relatively" loud and the "tinny" sound from the speakers attenuates the Dart a little pleasure. As a reaction against the "clacking" sound the pitches I have hosed all individual fields with special plastic fat in their scope and thus "stored". Now the results of an arrow sounds dull and no longer disturbing. The tone of the speaker is to improve further still a challange.
