Product review (5 stars): LOL I learned something after purchasing this my second wrench.
Well folks, Read Directions! This wrench workes really well, (IF YOU REMEMBER TO DEPRESSURIZE THE FILTRATON UNIT BY DEPRESSING THE RED BUTTON!) For three years I struggled to remove the filter bowl to change the filter under pressure. I broke the original wrench struggling to pry the pressurized bowl loose. Yeah Im a dummy, but I figured it out. Have a laugh on me.
