What Customers Are Saying

Customers overwhelmingly praise this socket set for exceptional value, reliable tool quality, and comprehensive SAE and metric sizes. Reviewers consistently highlight sturdy, durable sockets that grip rusty bolts securely, smooth ratchet operation, and a reliable push-button lock. The 12-point design with shallow and deep sockets supports everyday and demanding tasks. Color-coded bands—red for SAE, blue for metric—simplify identification. The compact, well-organized case is highly portable. A small number report case durability concerns or occasional ratchet issues, but most consider the set an outstanding purchase that delivers far more than expected.

Bad quality

Would Not Recommend

Bought a set like this over a year ago for work use and the quality was great and had no issues. Bought one last week and the quality is worse and cheap and the nut driver doesn’t even hold any of the bits it came with

Good Midsize Set

Would Recommend

This was the best set I could find that had a mid-range set of just sockets, 1/4” to 3/4”. I was not looking for a mechanics tool set or deep sockets, but the deep sockets are workable. I do like the compact box. If they skipped the spark plug socks and added in additional socks to make the range run from 1/4” to 1” that would have been super.

Good combo pack.

Would Recommend

This small combo pack has a lot of the bits and sockets that I need and use on a regular basis. It's also light and easy to carry. The downside is that there is only a couple of wrenches and they're small and I don't think there's much I can do with them. Then again, I didn't purchase this for the wrenches.

Nice tool set

Would Recommend

I had a set of tools very similar to this set and really liked it. But this set has more stuff than the one I bought several years ago. And really liked it.

Great first tool box

Would Recommend

This is a great socket set. It has all the necessary sizes and depths to complete almost any job. And the array of Allen wrenches and bits suffice as well. The case is very sturdy with metal latches. The only other thing I wish this kit had were the two socket sizes for spark plugs.

Not the same quality as older Kobalt

Would Not Recommend

These are MUCH, MUCH lower quality than my older Kobalt tools. (~2018 set) One of the ratchets broke on first use ! The sockets do NOT fit as tight as the older ones. These are almost unusable. JUNK !! DO NOT BUY THEM ~! I'm glad I have my old set.
