My husband, and isn't it almost always the husband, consistently blocks up the toilet. Normally it would take up to six or more hours of plunging every twenty minutes or so to remove the clog. The last time it happened was after hours and the plumber charged over two hundred dollars for the service call. This was a bad clog because eight hours of plunging and swearing did nothing to unclog it. Swearing actually doesn't help but it nearly always makes me feel better. I had read reviews of this plunger and didn't think anything could work that well, but I ordered it for next day delivery, and am I glad I did. The plumber did nothing to help the ongoing problem. It was clogged up again the next morning, which really enraged me! Two hundred bucks and it still wasn't working properly. As soon as the plunger arrived I ripped open the box and tried it out. I didn't have to put as much strength on it as before, and in less than a couple minutes, the clog was gone. It actually was less than a minute. This is a really great plunger, and I have never said that about any plunger before, but after years of my husband clogging the toilet, I had reached my level of thinking all plungers were the same, or useless. I just thought only hours of muscle strain and swearing were the answer. Not so. If someone in your house passes bricks daily and uses half a roll or more of toilet paper, do yourself a favor and buy this plunger. It really works, and with very little effort on your part. You may never swear again, but you can if you want to. I just wish I had bought this before I had to spend two hundred bucks. This is better than whoever the plumber was. He committed highway robbery and didn't do what he was paid to. This cost a lot less than the plumber, took almost no time and effort, and no colorful words from me. I bought an auger on the same order, and I haven't needed to use it yet. I have fewer clogs and I am not plunging every day like I used to. My husband appreciates the fact that I am no longer bellowing at him. Well not about the toilet anyway!
