Its not... Sufficient to do the things I've done effectively. Its definitely only good for being small, and maintenance free, and blowing up tires. When sanding drywall all day I used it to blow dust off myself. It's not the best tool for any job, but it's the smallest, oil free, and uses little power. It's what I have, and I'm not reccomending Itz unless you get a deal, and only count on it for refilling tires. It just can do other shit if you don't have an alternative.
