Mr. HeaterFuel Keg. - 1 lb. / 16 oz. Empty Refillable Propane Tank – DOT Certified, Black

I think this is a great product. If you frequently use 1 Lb propane cylinders this will save you money and keep disposables out of the landfill. That said, I purchased the fill kit which came with 1 fuel keg and I purchased an additional fuel keg so I would have 2. The one that came with the fill kit worked flawlessly. I will need to refill it soon so I went to fill the 2nd fuel keg that was purchased separately. The bleeder valve does not work. It will not open to allow trapped air out so propane will not go in. I should have checked it sooner. The return window closed 25 days ago so I will have to call customer service tomorrow and hope they will replace the bad bottle.Update: Customer service was excellent. Unlike others on Amazon it was hassle free, no delay tactics, no ridiculous hoops to jump through. The gentleman I spoke with was able to identify the issue quickly and had a solution to the problem. It was nice to speak with someone who understands their products and stands behind them.

I have purchased the Mr. Heater Propane Tank Refill Tank and three bottles of Mr. heater refillable propane bottles.They are easy to fill, and are reliable.I would however recommend that if you buy these bottles, also buy the brass tops and ditch the plastic ones that come with it. The brass tops have a seal and are a better way to prevent any leakage.

Well, mine doesn’t bleed off either. Just like some other reviewers mentioned my bleeder valve is completely blocked. I kept over filling it as much as my nerves would allow. Plus side is this thing can handle double what it’s rated for. But after you fill it, wait for 5 minutes and you’ll hear it randomly bleed itself off, with the bleeder closed. lol I just can’t trust it, fantasticUpdate - ALL USER ERROR. Beware that this bottle requires you to use the Mr heater branded refill kit. There is a small button that needs depressed inside the threaded collar in order for the bleeder to work. It’s a safety, makes perfect sense and works great

The fuel keg bottle is well built and very solid. You could probably bounce it off the ground without putting a dent in it, but, I wouldn't recommend it. It might go "Boom". The brass connector is really solid also. But, that bleeder valve. Oh! That bleeder valve! I've purchased eight of these bottles , two from this vendor, and four from a local vendor. I've already had to return two bottles because of that bleeder valve. I had no problem getting the defective bottle replaced from the Amazon vendor, nor one bottle from my local vendor. The Amazon return was quick and easy. Just make sure that you vent all of the propane from your bottle before you return it. But, my issue is with that cheaply made bleeder valve. It appears that the little piece that turns to open the bleeder valve is made of some type of aluminum or pot metal. It can already be white with oxidation when you receive the bottle. Several of my "new" bottles were in that condition. One that I bought stopped working at the first opening of the bleeder valve. It hissed with escaping air for about one second and then stopped like it was clogged. I bought another one that worked the very first time that I filled the bottle. The second time I tried to fill it, it started venting, and then just stopped. It was like the turn valve just snapped off intrnally. It would never open again when I turned the valve. So, the Fuel Keg folks need to take another look at their design and make the bleeder valve a little more robust. In the mean time, I would recommend being gentle when trying to open the bleeder valve. You can't force it. It either opens or it doesn't. Just start filling the bottle, and turn on the bleeder valve until you hear it hissing, and hold it there until it's filled. Don't over turn the valve. The good thing is that they can be returned if defective. And when they do work, they work very well, and they make refilling the bottle a quick and easy task.

So far - I might now prefer these over the larger competitor. They are a bit heavier (than flame king), but it makes them feel higher quality. They DO need a filler kit - or you won't be able to fill them. I have a little buddy heater, and it fits fine in the base. I love the little twist valve on the neck of the bottle, that allows fo rletting off building pressure when the bottle is being re-filled, This avoids having to use a tiny hex key that has to be used w Flame King. This is a great product for a good price!

Worth the money. I've refilled it many times already to get it's worth. If you already have big propane tanks for stoves you must get this. Easy refill. Good thank quality.

So far, so good. Decided to get rid of the older (dangerous) 1 lb propane cylinders that I had been refilling, with questionable success. This appeared to be a better option, and obviously, much safer. So far, everything has worked just as described, and all seems well. The tanks fill quickly and completely. Good job (Fuel Keg) Mr Heater !
