Very nice portable air tank. Light and easy to use for an old guy like myself. Definitely worth the money. Definitely recommend.

Je l'ai acheté comme réservoir auxiliaire pour utiliser avec une compresseur 5 gallons et ça fonctionne très bien, j'ai donc un compresseur portable et du volume d'air si j'ai besoin en plus d'une tank portable en cas de besoin. Parfait pour de petit atelier.

Not inexpensive but as long as you don't run over it, it will almost certainly last you your lifetime. If you are a buy-it-once person, do it - you won't regret it. If you aren't, buy a steel one for about half the price and it will probably rust out from the inside in about 10 years like mine did. Upon receiving, I loaded it up with 125PSI, closed the valve, and left it in the garage for a week - no air leaked out. Then I opened the valve and left my own personal hose (I prefer a long one) and fitting on it - still no leaks. So, the quality from the factory is very good. Welds looked nice and the paint job was good quality. Also, it has a water drain. Very few of these portable tanks have proper drains in the bottom.

When I picked the box up from the porch, I knew that I'd be glad that I bought this tank. I've owned steel air tanks in the past, and while I did expect this one to be lighter than them, I was surprised just how much so. Another pleasant surprise was the additional stabilizer on the bottom of the tank. Rather than having only one, as shown in the first five photos, there were two, as shown in the sixth photo of the tank near a compressor. I did quick leak test--admittedly for only a few hours--but the pressure was still there with no loss. Also, I like the form factor: longer and smaller in diameter than typical tanks of similar capacity. This is my second purchase of a California Air Tools product, and it probably won't be my last.
