At 52 years of age, I can tell you I have never owned a worse plunger. Today it actually broke from use. The rubber ripped where the stick attaches. That however turned out to be good fortune as now I can replace this “plunger”. It never plunged a toilet well and I couldn’t justify replacing a “working” plunger. I cannot convey how much worse of a plunger this is compared to a simple wooden handled plunger. You should almost buy one just to see how poorly this plunges. I would estimate it to being 30% as effective and only better than no plunger at all.
