What can happen with violet wands, though, is that the collet can splay from use.  If you look down into the nose, you may see four metal fingers that make up the wand's collet.  The collet is the piece that holds the parts in, and the fingers provide a 'friction grip'.  These  fingers can splay slightly over time or if you use slightly too large parts in it or especially if you push acessories too far in.  Your wand also may not have received precision factory adjustment if it is new.

Wand adjustment is part of your wand's maintenance. And adjusting your wand is easily done. If you use lesser quality 'rough cut', handcut or other type homemade accessories in a wand, such as some smaller vendors sell at fetish events you definitely will splay the collet and need to adjust your wand more frequently.
