The keycaps won ' t be a huge deal to most people , mostly just enthusiasts . In general most keycaps are made of ABS plastic which tends to wear down fairly quickly from normal use . You may have noticed that after a year or so some keycaps on your keyboard will start to get smooth and shiny from wearing down , making your keyboard look a bit off since some keys will shine and less used keys won ' t . It can also make it less satisfying to use since more heavily used keys will have less grip . PBT plastic on the other hand is more durable and wears down much slower they easily last 10 years , and Ducky PBT caps are rather thick so they feel very solid . PBT is also more gritty and textured so you get a better grip on them , most people find them to be more enjoyable to type on . And lastly , because they ' re dye sublimated the lettering will never wear or peel off . As for silent switches , they should be very similar to reds . The only difference from what I can tell is that they ' re quieter and have a smaller key travel distance 3 . 7 mm vs . 4 . 0 mm .
