High-quality.

I received these tools a few days ago and have used two different sizes multiple times in my garage-based bicycle restoration shop. They seem well-made and have a solid feel. I appreciate using Allen wrenches shaped like screwdrivers instead of the bent or triangle-shaped ones. Also, applying extra torque for rusted screws with a ratchet is precisely what I needed.

I am using these with a torque wrench for bicycle repairs. I was initially skeptical about buying these due to the off-branding, but they are good-quality tools. I measured each socket on its three sides with a Park Tools digital micrometer. The 10mm hex measures 9.96mm, 9.95mm, 9.96mm. In fact, all of the sockets have the same tolerances. They fit nicely into their respective sized bolt heads.

I haven't used it yet, but it arrived in a blue case. Regardless, I don't mind; it's a useful addition to my toolbox.

I often misplace smaller tools and struggle to locate them when needed, including hex bit sockets. Recently, I ordered these with the hope that having them in a case would help me keep track of them. I'm glad I did. Upon receiving them, I opened the package and found them to be well-made. The real test, as "they" say, is in the usage. I immediately took them to the garage and started working on a motorcycle that uses many of these fasteners. Each socket fits well and feels sturdy. The bit's length allows me to reach the fastener and clear obstructions with ease. As for their durability over time, I cannot say for certain, but the steel feels hard and should last with proper care. Overall, it's a great deal, especially considering the price.
