     These replacement springs are made to address two common issues with NMB's 725 series switches, commonly known as "Space Invaders" or "Angry Bears". Firstly the original springs have a tendency to get lost while opening the switches or even just pulling keycaps off; these new springs can not only replace the old ones but their shorter length and thus lower static load reduces the "jumping bean" effect so that they are less prone to being lost. Secondly some people dislike the heavy weighting of the original springs, particularly near the top of the stroke where they are especially heavy; while the original springs vary in weight across the many variations of the original switches these new springs are several grams lighter than even the lightest of the originals. Additionally their shorter length makes them much lighter on the top of the stroke, more similar to MX, Alps, and other common mechanical switches.
