💡 What's the difference between wobble and standard extensions?
The key difference is the angle you can work at.

• Standard extensions hold the socket straight and rigid
• Wobble extensions let the socket tilt a few degrees
• Tilting helps when the bolt sits at an odd angle
• Many mechanics keep both types in their toolbox
