Nice quality, except the container.

The product boasts excellent quality and durability. While the metal box it comes in is quite flimsy, that didn't concern us.


The sockets are robust with thick walls, and they performed admirably for the task I required. It's an excellent value for the money. The only downside was the handling by FedEx during shipping, which resulted in the complete destruction of the box and carrying case. I reached out to the seller, providing photos of the damage. They promptly responded, and within a week, I received a new carrying case. While the carrying case may be on the lighter-duty side, it won't pose an issue if you care for and maintain your tools.


To be completely honest, I have no immediate use for these sockets. I initially needed Starks 1-5/8 to 3" set with a ratchet, which I also purchased simultaneously with these. However, I thought to myself, "Self?" and I responded because I knew it was me... and I said, these are too cool to pass up. The bigger justification is that if, by any chance, I ever need a socket this large, the odds are that I won't be able to conveniently pick one up at the local parts store. I sincerely hope I never need this set, but in the event that my nuts get that big, at least I'll have the right tool for the job.

The 4" socket on the right is a substantial 18 pounds of Chrome Moly. I extensively searched for large sockets, and this set offered the best price, beating competitors by a factor of 3-6 times. The case they come in is metal with metal handles, though it's a bit flimsy for such heavy sockets. However, I suppose if they had to cut corners somewhere, I'm glad it was in the carrying case.
