Perfectly adequate.
This was exactly what I needed for working on a deep set nut when replacing struts on my minivan. Seems sturdy enough and fit the 18mm nut fine.

I won't know until I remove my tire
Had a Toyota, so I got the 21mm. Sold the Toyota and now I have a Honda, so I got the 19mm. Fits perfectly! Leverage is great for removing lug nuts that got impacted on. I have a 1/2" drive breaker bar, extension, and deep socket. Hardly takes up any space in my trunk and changing a flat tire will be super easy now. The 19mm deep socket fits well and won't rust. I think.

Great socket to round out the metric only set.
Nice addition to my metric set so I don't have to pull one from my imperial set. The marking is great and easy to read. Good deal for the money. All positive thoughts on this one.
