A recent reviewer, Susan Khoury, wrote: “The operation manual has a number of warnings and cautions on compressors that do not apply to this tool and appear to be taken from another manual for a specific compressor. One warning about exceeding the tool speed (8500 RPM) conflicts with the specifications listing the tool speed as 9000 RPM.” I may be able to provide some context to this discrepancy. In August I purchased an identically appearing tool. The manual for that tool is for an AP9515. The tool here RP9515. Other than the product name, the manuals are identical. The tool speed for the AP9515 is listed on the tool as 8500. Are these the exactly the same tool, both manufactured by Jax technologies, probably. They look the same, they weigh the same, they have the same torque, etc. Is one a newer model?—well Amazon does not give me the information to know. So, does this really make any difference?—no, unless you don’t care about paying twice the price of the other one. So, assuming these are or are darn near the same, here’s what I wrote about the cheaper. I really like compact air impact wrenches. Even with the hose, they can access areas a battery tool can’t get into, and have the power most corded drivers can’t achieve. But even when access isn’t an issue, their weight, size and balance are greatly appreciated—certainly compared to my full size tools which are far heavier, with the weight poorly balanced in the hand. Now I’m a hobbyist, but one who regularly handles “pro” level projects—just not as frequently. Recalcitrant bolts on an old Corvette, control arm and other suspension components on a built up Jeep and Suburban are my typical tasks. A bit of extra vibration isn’t an issue, as I’m not doing this 6-8 hours a day, day after day, but fatigue from a very heavy, poorly balanced tool very much is— I know, because I have a couple, one from an “industry leader.” So I find that 95% of the time, if I’m using an air impact, it is my compact Aircat (still going strong after 5 years). I usually keep it stashed in my Jeep as I have onboard air, but I still find myself going to the trouble of retrieving it for home projects. So this is why I was predisposed to trying out the Aeropro mini, along with the fact that it costs half of what another Aircat would be. I’m so very happy I did. The Aeropro turns out to be everything I like about a compact impact, and goes on to have the best feel in my hand of any air tool I’ve used. For my medium sized, men’s hands, the fit is perfect, yet there is enough space on the handle that a larger hand should comfortably fit. Equally important, for me, the balance is perfect. I find myself picking up this tool when I have no need for it, just because I so enjoy holding it. Ultimately a tool should be functional, and good ergonomics is a major contributor to optimal function. There’s no way of knowing, after only a couple of weeks, if it will be running as strong after 5 years as my Aircat, but overall, this is a great tool. Now back to the present. As opportunities arise, I’ll use and compare both and update this review within a couple of months. If I discern a difference, or the manufacturer informs me of one, I’ll add the information to this review—until then I discern no difference but price. 4/02/2023 Update: As of now, no manufacturer has contacted me to inform me of a difference. I still use them interchangeably, and continue to not discern any difference. I don’t use them often, but I do use them regularly—they continue to function as new.
