3/4” Impact Wrench

I am diesel mechanic and was so excited to receive this impact wrench as it is a tool that I could use every day at work. However I was disappointed when I got to work and started using it. It works okay, but compared to some other brand name impact wrenches that I have used the power behind it is not as strong as others. Does it work absolutely, would a non mechanic find it useful to have in their garage absolutely. But as a mechanic using it everyday I feel like it doesn’t have enough power behind it. Will I use at a back up incase my other impact wrench brakes absolutely.
