good range, not the best design

Getting them to work well takes a little experimentation and practice. If the hole is too small or your iron isn't perfectly aligned, it will create a lump of plastic that will block the filament from entering. I found that inserting with the screw already helped, but heating the insert wasn't that easy.

Pros
  • Practical application
Cons
  • Something different
