Great little compressor
Imagine air without a cord! It has a small tank, so it has to run a lot if you have a heavy demand, but for remodeling, airing up tires, etc., you can carry it with you so easily. I am going to try a slightly larger remote tank. I carry it with me in the back seat of my pickup and never worry about flats, driving a nail, etc. II HIGHLY recommend this little giant.
