Yea, if the wife had'nt mentioned it i never would have checked the beauty shop. I deal with a 40 breeder so i can take the time to manicure every last inch and still not spend all day doing it. I could see them not being nearly as useful in a larger tank. Where i really noticed a difference though is trimming red tiger lotus, I have a hell of a time seeing which leaf im cutting off in a field of stems, with the super fine tip its much easier for me to pinpoint.
