DAKCOS 17 Pieces Impact Socket Adapter Set, Includes Reducer, Universal Joint Socket Set, Grade Drill power Socket Adapter Set,1/4" 3/8" 1/2" Drive

I do not have anything in the case anymore but I can assure you that this comes with everything you're looking for and it is a keeper. The quality and durability of everything was what I was looking for. And the value for the money is obviously something most of us are looking for when it comes to functionality and having a correct size. As far as the impact rating is concerned, I would say again that for the size and functionality it's right on point to what the specs say and having something like this is definitely something you would want in your toolbox!

PROS: Solid construction, built like a tank! Also, there is a wide selection of adapters to choose from, depending on what you need them for. I REALLY LIKE the clear markings on the tools themselves that tell you what sizes you are adapting from/to (see third photo). Decent value, about $2 apiece, but not a crazy good deal. CONS: The "case" is not really a case, but a foam mat...a REALLY THICK foam mat. Sort of weird. It had to be thick to fit the 3/4" adapter in the bottom middle (see second photo). Even the top that looks like carbon fiber is just foam. Would have preferred a true case. Overall, this is a durable set with lots of options.

This tool set seems to be very well made. It is a very complete set of adapters. They are rated for impact tools, so they must be heavy duty. I have not hit them with any heavy work yet, but so far I like this set. I love the foam storage tray that it comes in. It is a perfect fit for the tool box drawer and keeps the adapters organized and easy to locate.
