You know, @Dewsy92 is right. It always works, and I rely on it for my melon sword all the time. BUT that being the case, if I look down and see that the tool is red, it still makes me nervous, even though I KNOW it works. So +1.
+1 I'd like to see it somewhere around 50%, I just don't have the nerve to risk an 850k tool on 900k worth of donations.
