How can i get a cartridge to last more then a month or two i have 5 when you buy it for life what is the life span do you have anything that will last

Good advice for anyone is to NEVER but/install ANY aftermarket cartridge in a Moen single handle faucet. In all these decades I have never see a single one that worked out. They either stick from the off position, bind, leak, etc, etc, etc. ONLY use genuine Moen cartrifges! Brass or plastic; doesn't matter. Just use OEM Moen. I actually now prefer plastic only because after 5 years, you usually have your hands full getting a brass one out do to green corrosion. But thet's just me.
