Great quality
This thick plastic wrench is a big improvement over one I bought a few years back. This one is very sturdy and it's great to unscrew the blue housing for the filter. However, if the housing is really tight, you might need two of these wrenches. They are inexpensive enough to buy two.

Needs to be stronger
These filters take a lot of pressure to unscrew and this wrench appears to be the same as my original which broke last year when changing the filter. Need to be made from something stronger. I always spray the threads and O rings with silicon when I put them together but they are still difficult to remove. I only change once a year because there are just two of us and the toilet water does not go through the filter.
