$10 Upper Ball Joint Socket - Really

I just bought this and used it. Wow, super easy to remove the ball joints. Used my impact as well. The socket says not for use with an impact. But I was up for an adventure..
Yeah, I just did a few impacts at a time 'til things started to move.

I've since seen this same tool elsewhare, like at NAPA. Not sure if any other brands are better/stronger.
