Q: How did the tool/equipment function as far as saving you time?

A: In terms of overall use, most impact wrenches are fairly on par with one another from a time perspective. That being said, the power output of this tool for its size and weight is good, and its easy-to-operate controls may save a little time and create a better end-user experience.

Q: What kind of setup was involved before using the product?

A: Like most air/pneumatic tools, the only setup required was the installation of the appropriate quick-connect fitting and oiling of the tool.

Q: How easy was it to use?

A: This is as easy to use as any impact wrench, but the lighter weight compared to one with an all-metal housing makes it more enjoyable to use over a longer period of time. In addition, the controls are easier to operate than those of many impact wrenches.

Q: How was its packaging? Did it come with any accessories?

A: The AIRCAT 1125 comes nicely packaged in a cardboard box with a declaration of conformity document and an operating manual with warranty information. 

Q: Was there a manual included? If so, did you use the manual, and was the manual easy to understand?

A: Like many air tools, the manual provides various warnings and precautions associated with the usage of the tool. It also provides information on proper air supply, a parts list with an exploded view, maintenance information, and warranty information. 

Q: What features did you like?

A: This impact wrench combines the directional control and power output into one lever. The counter-clockwise direction is automatically full power, and three different power output levels are provided for clockwise operation. This prevents the possibility of accidentally trying to remove a fastener with the impact wrench in a lower power output setting. The lever is also nicely positioned at the rear of the tool making it easy to access and control (even with heavier gloves on) without being easily bumped out of the intended position. Each setting offers a nice detent as well to help prevent unintended mode switching.

Q: Is there any way you could think to improve or add to this tool?

A: None that I can think of.

Q: What types of jobs/repairs did you use this tool for?

A: I used this in various typical impact wrench use cases: removing and installing lug nuts, removing crankshaft harmonic balancer bolts, flywheel/flex plate bolts, brake caliper anchor plate bolts, etc.

Q:How does this tool compare to other tools you've worked with?

A: As previously mentioned, the control mechanism of this impact wrench is superior to others I've used in the past, making it far easier to operate while wearing gloves. 

Q: Is there anything you had questions or concerns about in regard to the tool?

A: While not necessary, some users like to keep a protective boot/sleeve on their impact wrench. The AIRCAT website shows the 1150-BB on the product page for the 1125, but the 1125 is not listed as one of the compatible models for this protective boot, so it is unclear as to whether or not one is available for the 1125.

Q: On a scale of 1 to 10, how would you rate this tool overall? Why?

A: Eight out of 10. This tool seems well-designed, has good power output for its size and weight, and is comfortable and easy to control and use. I cannot yet vouch for its long-term durability when exposed to the drops and other abuse impact wrenches are inevitably exposed to in the shop environments throughout their life.
