I've been using these on my Creality Ender 3 V2 for two months now and the change has been huge! With the stock springs on the ender, I would have to level the bed every 2-3 prints, more frequently on larger prints that are harder to remove. With these nibs (set with pretty decent tension) I didn't have to change the level after 30+ prints in all sizes. I'm really just guessing how many prints there were because there have been so many since I leveled the bed that I honestly forgot! Installation is incredibly easy and the improvement is such that I honestly can't believe Creality didn't make it a standard feature in their factory. The stable print bed almost solved my adhesion issues, transforming the printer from a whimsical toy into a fully functional tool that I can really rely on for larger projects.
