Okay, I've been looking at this product for months. BOY, I'm glad I finally bought it! My main reason I wanted this was because I do woodwork in my only car garage. It's a FULL garage, let me tell you. Along with my various woodworking tools, wood, hand tools, brooms, mops, Harleys, car tools, etc. etc. etc. I collect a lot of dust. Sometimes I have to break my compressor, which I don't use very often to blow out the garage. It works great but it's not perfect because it's small and I have to constantly wait for it to build up pressure. Especially when I have to do some finishing I try to blow it out completely. I finally bought this little fan. Now I buy tools for a small local lumber company and work a lot with Dewalt. This often gives me the courage to bite the bullet and try a new tool, I know they will take care of me if that doesn't work. As always, it was worth the money! Well, as far as accurate air delivery goes, my compressor is probably still running better. However, for longer range this is much more powerful. In general, it's much more useful. If I have to remove the dust from small cracks, I can still break the compressor. For the majority of my dust I will use this. Just in case, I tried it at home on some hard-to-reach spots. It works damn well for cleaning out vents and dust bunks in those high peaks you can't reach! As a bonus I will use it on camping trips to blow up mattresses or floats with the included attachments. The only thing I would have liked would have been something to read the wind pressure more accurately, but that probably wears out the motor too much, so I agree it doesn't. Leaves. If you only had a small amount this might work well, but as expected it's not exactly ideal for this situation. I didn't expect that and didn't want to use it for that anyway.
