Comfortable !!
These are great. Glad someone took the trouble to make a quality product for such a mundane item. Pressure is applied more evenly. Non-slip. I have a flatter than normal nose bridge and these work so much better for me.  I got these to replace a missing pad on one of my pairs of glasses. I liked them enough to go through the trouble to replace the functioning pads on another two pairs of glasses.  Still have another 5 pair to spare. These are no easier or harder to install than other nose bridges. In other words they are still a pain to install but that is just a general issue with nose pads and I can't take off a star for that.
