Review on Optimized Search: Sunex Tools 4-Piece 1/2-inch Drive Locking Extension Set with Chrome Finish by Nale Dunn

I currently use them to tighten wheel eyelets in the 80lbft-150lbft range, mostly 150lbft. They do the job well enough. This means they work well in lighter applications. The locking mechanism is reliable. Reviews of 1/4 and 3/8 versions show errors, but this is to be expected with smaller moving parts in high load applications. I would buy the 1/2 set again without question. I also paid 38€ including shipping. I don't mind getting version 3/8 but not 1/4. Sunex quality always comes first.
