They appear sleek and well made. However, I will not use them in high-speed applications. Like other people, they were used to fix the horrible Crosman trigger in some airgun models. I started with a stock 8x5x2.5. The trigger was much better, but I felt it could be improved. I ordered this 9x5x3mm and the trigger is great now. I tested the solution by hitting the buttocks on the ground and couldn't get it to casually fire. So this seems like a safe solution. This made the cheap airgun more stable and pleasant to shoot. I used one and there are 9 left but oh well. Hope that helps.
