Product review (3 stars): I broke one, so I bought two more!
I broke the first one that came with the filter. The handle snapped in half, so I bought two more (go figure). I am using the two new ones like a T-handle. Like some other reviewers, I struggled to unscrew the filter body from the mount, even though I had shutoff the water to my house, opened up a couple of faucets, and released the pressure via the red button on the filter mount. The handles flex under full load, so that doesn't help much. I've also been using food grade lube on the threads of the filter body. I doubled up the amount of lube applied this time.
