Great tools, have both 14mm and 5/8in drives and the ball joint swivel is so much better, smoother action than any of my other swivels, and when it comes to spark plugs u need to have smooth swivel action or else u can break the ceramic so fast. I don't buy cheap tools, it's not worth it when they cost you money in broken parts, broken tools, rounded off fasteners, hard to reach, etc... I'm a professional mechanic and cta tools are a great option for all. Anyone can utilize this items quality and sturdy build construction. They make top quality tools to get the job done right the first time and at an affordable price. Gearwrench is another top end tool along with proto/Stanley but stick with the proto made versions, gearwrench is Apex tools so if u didn't know that there u go. Apex is compared with matco, snap on, Cornwell, Mac, sk tools, etc all the pro tool companies. And cta is a less known company like grey pneumatic and ASTRO pneumatic both great tools and even sunex has good quality tools can't beat their prices. But cta is a European tool favorite I believe and so I'm glad to see them here in the US now being utilized.
