If they can not support their claims why do we fear their threat of law suit. If it does what they say, prove it with competent data and we will go away and/or support their product. If it does not, screw em. But, do not be afraid to challenge their bogus claims which are/can not be supported by competent data. Filter before, filter after, yada, yada, yada. Support your claims or go home. I am quaking in my boots waiting to be sued by a company which can not support their claims. Paul W. Weakley 110 Shoreham Lane Williamsburg, VA 23185-4932 MTOA #3668
