I tested and used all the tools and it worked just fine on the first try. The impact gun produces a lot of torque, and the air ratchet performs well. Even the angle grinder performed great, only using little air and boasting a large rpm range and power.
This is an excellent kit. I've used all of the tools without any problems. Because I'm new to this, I make sure to check if it's 90 PSI on my air compressor. Also, I still have to break a lot of bolts by hand, but this still comes when I'm loosening things up, running nuts, cutting, and so on.
Great for DIY tasks! Tools are of good quality, everything functions properly, and the casing is nice and well-organized.
This item was quite reasonably priced. Everything works flawlessly.
Sturdy toolset!
