You don't NEED this wrench, but you are really going to wish you had it ten minutes into the job when your pliers handle jig pops out for the fifth time and you start cursing at the stuck cartridge. The wrench applies the torque centrally and equally to all the fins, making the job infinitely easier. I tried it without it and then bought one. It is absolutely worth the money.
