  • Works great, but I can see the label wearing off. I would have paid extra to have an etched label that won’t wear off over time. Other then the label, for the price the tool appears to be good quality
  • This is not a true 21mm socket. Got this for my wheel lug nuts which I measured at 21mm. I ended up getting one at a local parts stores that does fit.
  • Sunex is a good brand of tool and I’ve never had problems with any of their stuff, this socket included.
  • As title stated, it’s an impact socket. Used multiple times over the last month without fail.
  • Nothing to dislike
  • Bought for lug nut removal on F-150,Seemed well made, good fit.
  • Dunes tools are great
  • I work in a busy Shop this sock gets use every day I have not had one issue with it honestly I feel that it’s better than the expensive snap on brand
