I have their cooling pressure tester, it has the most adapters out of any kit I have seen and the universal ones work well. I have their axle nut set as well. Both great products and used in a professional environment everyday.
I don't have their ball joint set but it does have a lot of adapters with it, looks like a solid kit.
And I'm going to say it, their cooling pressure kit was way more versatile the. My snap on one it replaced.
