Review on Superb Wrench SPBW 1 Housing Diameter by Thomas Ramirez

Having spent extra money on this key I couldn't be happier after using it. The longer handle increases the torque significantly. While the old plastic key broke after I turned it with all my strength, this one only turned with little effort. The second filter also rotated with ridiculous ease. So I invited my wife to shoot the third one. She has no upper body strength and was still able to turn it quite easily. Unlike the ribbed plastic grip that digs into my hands, the rubberized finish is comfortable. And the thickness and heaviness - WOW. This is a real tool. This thing is heavy and twice as thick as I expected. These guys aren't kidding. I couldn't be happier. Oh, and after I put the filters in and screwed them in - no leaks, first try. With the plastic wrench I had to tighten, check for leaks, tighten, check for leaks, sometimes 3 times - what agony. This one - zip, zip, boom-boom, you're done! I may sound crazy but if you've struggled with that junk plastic key and possibly broken it, just make sure it fits your system, buy it and never look back. Oh, by the way, I have the iSpring/123filter.com system, so I can confirm that it works with it. If you're wondering if it will fit your system, go to their website, print out a clipping sheet, cut it out and put it on top of the filter. You can measure it too, but mine was borderline so I had to.
