Query: Does what I purchased it for

I purchased this unit primarily to put air in automotive tires. I was able to do so without issue, no leakage when applying the nozzle to the tire. I bought another nozzle for it to use for blowing sawdust off of sanded objects. It did this well also, although frankly a bigger tank would be better suited for any major projects, but this wasn't why I bought it. Regarding the loudness of operation as mentioned in other reviews, the first time out I made sure I was working in the garage with the doors up, and prepared for rock-concert volume. I had to laugh when I switched it on. If your idea of a rock concert is Neil Diamond, then yeah, maybe this unit will seem excessively loud to you. (No offense to Neil, you've had some great songs over the years buddy, and ear protection is always a good idea, but c'mon...)
