Players Wanted explains why the Anti-Fog Unit (AFU) from Novritsch should be recalled. For those who have purchased this, they can watch this video to make their own conclusions... "We decided to purchase 2 Novritsch Anti Fog Units and 2 Exfog units and put them to the test. What we found out about the Novritsch AFU should shock you. These units are an accident waiting to happen. Check out the video for more information but simple BB strikes at ranges that are to be expected at airsoft fields led to catastrophic failures in the unit."
