I purchased the sunex brand master socket sets because we use this brand tools at work and we have never been let down on their quality and I wanted sets that are all inclusive, including torx bits, shallow, deep, and swivel sockets. these kits include all of that plus a wide range of extensions and a swivel to put either the shallow or deep sockets on if I need that particular set up without having to purchase those whole sets which are a lot more money. I work on construction equipment and believe me if you ever have to loosen a rusted concrete coated nut and bolt the strength of these impact sockets and the grip on the side wall of the nut is mandatory, other sockets just grab the edges and that will quickly round out the nuts and bolts and force you to cut them off.When I have to do any kind of interior work dashboard work or manifold work these are my tools I go to. the case has every single thing you need to take apart dashboards or anything else. All the great sizes all the swivels off the extensions man this thing has been a lifesaver. I use this with my Milwaukee quarter inch ratcheting tool and it gets the job done quick. Only issue I have is you can't read any of letterings. so try not to get them too dirty. Love the case has four clips on it so you they will never drop out and fall on the floor. It's very well organized sturdy very well made. I love these things. And I have put these things through the wringer. And they're still going strong.No impact hex to 1/4" adapter, but this appears to be true in all their master sets. Didn't affect me as I had many of those already. As long as you don't drop or throw the set case, it'll hold all the bits in place no matter the orientation (as long as it's properly closed and latched). Highly recommend this set to anyone who needs tools for a livingPerfect. I agree with the things many said about this set... hard to read, good case. the universal or flex sockets are really good! Never used ones with such a perfect balance of friction. They make it really fast to start nuts in areas difficult to reach.I think they are great set of impact sockets. And have a large range of what you need.Nice complete set for the price! Long, short, wobble sockets plus extension. Not gonna get any other brand to give all this at this price. The quality is as good or better than everything else made in Taiwan.I have had these sockets attached to my Milwaukee 1/4 impact daily for over a year and I do not notice any difference in performance.The set does not skip sizes!The fit on fasteners is fantastic!Am I able to fit every swivel/universal socket into a place that a pinless set would fit?No, but you can afford to buy complete deep, shallow and swivel Metric and SAE 1/4 set for half the price of just one tool truck Metric impact swivel set!This is a great set. Complete and tough for small sockets. My co-workers use it as much as I do. The tiny wobblies are life safes in tight spots. Little pricey but worth it.Excelente calidad, muy bueno para pistolas de impacto tanto eléctricas como neumaticas, cumple con todo lo establecidoExcellent quality I use these professionally on a regular basis you get a lot for the price.
