I replaced an expired 5 gallon portable air tank with this Wilmar 11 gallon model, and everything seems to work as intended. I did not try using the included air hose and chuck, since I switched over a coiled air hose and custom made chuck from the old tank. However, the stock air hose and chuck appear to be sufficient for many users. The price (about $40) and service were excellent, with prompt delivery. I would recommend getting this 11 gallon tank over a smaller capacity tank which can cost nearly as much.
