Glad to be the first to review these soldering tips. If you burn soldering irons quickly and find yourself buying new cheaper 25-35W because the tips are worn out, great! Originals to ensure a secure fit. Their diameter of 0.4 mm is ideal for SMD soldering and all other work. I've been using one of these for about a week and am not experiencing any deterioration or rapid wear. When I do I have 9 more in separate packs :) Highly recommended, watch the video for a closer look.
