Extensive corrosion, pitting, scaling. Product was advertised as “new”, what I received had been used and stored in a corrosive environment.

I have extensions made by other brands; Dewalt, Milwaukee, … and it makes them feel envious. It’s nice to hold in hand and the mass and girth stick out.

Works great I use it everyday at the dealership I work at when I do brake jobs. No more sockets slinging off and hitting me in the face. Socket stays on unless I unlock it.

Great product. I use it professionally and it holds up. Bought it to replace my snapon that kept breaking after a few months. Awesome product.

I use this item in a vehicle dealership , with a high volume of vehicles we maintain and repair. I use it to brake loose bolts with my half inch impact gun. I tighten suspension parts and abuse this adapter and so far its awsome and continues to work day and day out. I love this item. Its ahigh quality tool with a reasonable price. The price is what got me but the quality is why i kept it.

Very well built but it has pin retention instead of ball retention. If you are looking for one with ball retention, this one is not for you

A quality tool with a great warranty from a brand that I trust. The extension works well and as it should without fail and it is made in the United States.
