poorly designed

Most RO/DI canisters become tight after awhile. This wrench is made poorly. Its to small to reach the top of any canister in order to receive the strongest position to brake loose the seal. It only rides up a few inches. When putting on pressure the handle bends from to much nylon made in the handle, the more nylon thee more it bends. I wouldn't advise to buy this one..... THIS ONE IS JUNK. Hope the business will seek a stronger piece of equipment....The wrench needs to be strong.....

RO Housing Wrench

One of the best wrenches for the money. You can't beat the build quality of this wrench. It'll beat any canister wrench on the market. It only comes in black, but what other color will you need for a wrench? I've tried a white wrench and it's not as cool. Black is the color you want. The only reason I did not give it 5 stars is because I would rather have one made of aluminium for the same price. Buy it. You wont' regret it.
