    • Affordable and durable
These perform just as well as my tool truck sockets for 1/4 of the price. I’ve put these through the wringer, air tools, battery tools, stuck bolts, doesn’t matter. The quality of the socket is out standing. For what you pay, I have no complaints. The mold case is extremely durable and stands out in your toolbox. I can’t talk about their warranty because I’ve never had to warranty one. The female insert hasn’t rounded out in any of my sockets yet, they still fit nice and tight. Don’t waste your money else where. ... show more

    • For the price of this Sunex set on Amazon, it was my 3/8 impact set of choice - great quality for a DIY'er or even full time use
I was looking for a good 3/8 inch Impact set to go with my new Milwaukee 2754 Impact Wrench, and there were a few good sets in the running. I had it narrowed it down to the Sunex, Gearwrench and Grey Pneumatic sets. All of the sets were Made in Taiwan, and all were of similar quality. The Grey had a more polished finish, and was at the front of the pack, but it appeared that all three sets were about the same quality and perhaps even made in the same factory. The tiebreaker was the price - when I found the Sunex set here on Amazon for $54.99, it became a "no-brainer". The other sets were as much as $30 more depending on where you looked. (Note that checking back today on the price for this same set, Amazon and third party sellers are now asking $78 - so the price has gone up - at least temporarily). The prices for these sets are all over the map, with some sites even asking $175 for the Gearwrench set! One edge the Sunex set has on the Grey set was the sizes stamped into the sockets as well as etched - the etching wears off and having the size stamped on the side is nice. This Sunex set is of completely acceptable quality, and for a DIY'er is more than I need. I have used it to change shocks on two vehicles, and install a sway bar on my SUV, and they performed wonderfully. I have seen a couple of online reviews that claim the Sunex set is not a "true" deep socket, and that concerned me, but when I received the set I was pleasantly surprised to find these reviews wrong. The Sunex deep sockets are every bit as deep internally as any other choice, and that should not be a concern if you are thinking of buying it. Please note it is good to keep a thin coat of oil on these sockets, especially if you live in a high humidity climate. Over time they will show signs of rusting if you don't. Overall, very pleased with this set, and the price made it my set of choice. I am now looking for my 1/2" set! Thanks for reading. ... show more

    • Greatest portable 3/8” set
Sunex sockets are superior to any major tool truck brand out there. These are thin walled but have enough mass to break anything loose when used on a pneumatic or high torque battery impact. The case is slimmer than a laptop and can be slid in any bag without issue. This is my most frequently used and well loved tool in my toolbox by far. Sunex customer service is also unmatched by any other manufacturer. Slowly started to see Mac, Gearwrench, and Matco trucks carrying Sunex tools over the past few years, and hardly any warranties having the be filed for broken tools ... show more

    • Excellent thin wall 3/8 impact sockets
Been using these sockets with my milwaukee 3/8 stubby impact. They have been great, used some of the larger size sockets on the highest setting (roughly 250 ft/lbs rating) and they take the hits no sweat. The universal joint has held up well also, love that addition. Fantastic value socket set

    • Decent set
My only real complaint is they are a little snug on the 3/8" sockets so they can be annoying to get off/on your ratchets or gun

    • Nice kit.
I have had this for a while now and it works just fine for me. It represents good value as far as I am concerned.

    • Great impact sockets
Bought these last year and they've been great, in diesel field, warranty is also fast and simple, just send pictures of your broken socket for online claims and you get a new one within 10 days

    • I loved these so much, I bought the 1/2 drive set as well and love them as much as these.
I love the high quality case they come in. I love the sockets. They fit my drive well, they were slightly oiled so none showed up rusty. They are well marked and easy to read. The case also has larger markings making it super easy and fast to find the size you want. I was impressed with the case as much as the sockets. Everything has a nice tight snug fit. Nothing comes loose by itself. I liked it so much, I bought the 1/2 drive set as well and love them as much as this 13/8 drive set. This is a lot of high quality bang for the buck. You're hard pressed to do better than this. If you spend less than this expect junk. If you spend more than this, your wasting your money. This is Snap on quality for 25% of the price. ... show more
