I bought the first set for my EX21. The old clamps were still in good working order but I liked the simplicity of the Pegas and so I bought a set. I have NO regrets. They gave me less vibration and it's obvious that they are lighter weight. I love how they work too. So effortless and smooth. I DO feel that they are a bit pricey so I still haven't pulled the trigger on another set for my EX16 but at some point, after the world comes back to it's senses, I'll order another set. Maybe by then they will feel that the price is too high and drop it a bit. I know, wishful thinking.
