I dont know what these people are talking about, I never had problem with this. I actually log on because I just want to give this a review, I never do review anymore unless it gets my attention to be a really great performance.
I will give this a ten, IT is exactly similar to CP on/off. The only difference, on my opinion I prefer this NDZ. This is half of the wieght of cp. Everybody knows cp on/off is so Heavy. Almost half a lb I think. I have two of CP, red and silver. Back to NDZ...This NDZ does let me down, Oring, never had change it. Its been a year now using, and has never change it.
Those of you had problem let NDZ know, and ask them to replace it.
