Overall this is a good key to replacing the reverse osmosis filter. I am sure, like many others, that I have overtightened the canisters in my reverse osmosis system about 9 times out of 10 when I have changed filters. Last time I broke 2 of the cheap plastic wrenches that came with my reverse osmosis systems and ended up using a strap wrench to remove and reinstall the canisters. After this episode I ordered this metal key. The extra length and solid construction gives me just the leverage I need to get on and off canisters without breaking my knuckles or cutting my hand like I did last time when my plastic wrench broke while attempting to remove a canister. For example: • The length is perfect, giving you great leverage • Metal is much better than plastic • Rubberized grip Dislikes: • It already has rust spots • The teeth are too small • The teeth and metal edges are VERY SHARP!
