  • Quality brand at a great price
Style: 40 LB Tank
Propane is so much cleaner and quieter than using gas in a generator, but these larger tanks can be hard to find locally. This showed up ready to go and seems to be great quality. Same brand they sell at the ACE Hardware near our house

  • Seemed to be priced within 10% or so of a used one. Go figure??
Style: 40 LB Tank
I did the Facebook/Marketplace and Craigslist ads for a used one. So after a few weeks of looking for a reasonable deal, I gave up. Amazon's price on this (and I bought a smaller one as well) was within 10 or 15% more than some beat-up used hand-me-down. Your experience may vary. :) Anyway, works well, looks good and is 100% as well built as any other tank I've ever owned. ... show more

  • Nice tank
Style: 40 LB Tank
I bought it to have a spare and paid the same price as I did for a used one locally that doesn't look as good. So it was well worth the price.

  • Great tank
Style: 40 LB Tank
I use this for backyard blacksmithing. It is light enough to carry way out in the yard to my mobile forge. Doesn't freeze up quickly like the smaller tanks. Built well, no issues so far. Tip if you're forging for extended periods of time (or any other task). Put small wood planks or similar under the tank if you're using this on grass. Especially in cold weather. If you run this for hours, it will start to freeze on the bottom. It will stick to the grass and rip it up if you don't have something for it to sit on. ... show more

  • These work as advertised
Style: 40 LB Tank
We got two of these for our off grid property and they work exactly as they're supposed to. If I ever need another propane tank, I'll be coming back to buy this one.
