They're not as good as stock.
1. The removable cap is fucking annoying. I always super glued it
2. Some homebrew hates it since it's more sensitive.
3. It takes a little more effort to move it
4. If you move it in a cardinal direction, it doesn't exactly move that way, which is annoying. Like if I move it diagonally to the right, it will be off by a few degrees even after calibrating
