When I first started smoking a pipe I actually thought they were ridiculous. But, I got one one day and tried it I have used one on every pipe since. For me, I have jaw issues and the soft pipe bits give me some more give and doesn't make my jaw work so hard to clench. For me too, I really prefer to protect the stem. I hate dents in the stem. I buy them in bulk of the bay. One of the few things I don't buy from our sponsors, but its a much better deal.
