Mr. Heater Fuel Keg. - 1 lb. / 16 oz. Empty Refillable Propane Tank – DOT Certified

These work great when you follow directions and use a lot of the 1 lb tanks. Less than 4 refill and it pays for itself.

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.

WORK BETTER THAN OTHER BRANDS, EASY TO FILL, SAVE A LOT OF MONEY

This is a great product! As you can see from many of the negative reviews, there can be some re-filling issues that are blamed on poorly designed vent valves etc. I had several of these tanks that would vent for 1-2 seconds and then stop abruptly. I cut one of them open to see how the valve system worked from the inside. What I found was a very simple and well engineered valve system with no apparent reason for the mysterious vent shutdown. Upon reflection I have a theory. The venting and rapid expansion of the vapor causes a instant and dramatic temperature drop of the entire brass valve. If there is any moisture present around the internal vent mechanism it flash freezes stopping the venting process. After a few fills of each tank there is bound to be some humid air carried into the tank (think of the ambient air in the filling unit being pushed into the tank ahead of the propane on the first tank filled). I had 3 tanks that would not fill last Friday - today (Sunday) all three filled easily.Bottom line - if you have tanks that won't fill, give them a rest and try again once they have warmed up a bit. There's probably nothing wrong with the Fuel Keg.So, why the 1 Star for customer service?Customer service does not acknowledge my emails so I assume they get a lot of complaints about this issue and their solution is to ignore their customers. Says a lot about the company.

This showed up last night. I haven't tried to use it yet but I will in the next day or two in case there are any functional issues with it so I can get it exchanged... But, it doesn't look as nice as I expected either. I'm pretty sure the canister is new but it may have sat on a shelf for a while before being sold. The paint is fairly beat up and surface rust has started around the base ring. The brass valve is tarnish and dirty. The relief valve and ring are both covered in corrosion too.Update: I now have two of these canisters. If they looked like new products I would give them 5 stars. Functionally, they are fantastic. The integrated bleeder valve is perfect. Filling the canisters is amazingly easy. I can even use them to empty "almost" empty 20 and 30 pound cylinders before refilling or exchanging them. So there is no waste in the 20 and 30 pounders. Filling these cylinders when they are partially filled is just as easy as filling them when they are empty. Now that I have two of these cylinders, I've been able to recycle two arm fulls of the single use canisters which helps with space management in an already cramped garage. If they can figure out a way to get these delivered without having tarnished brass, scratched paint and rust, they would be perfect. As a side note: If you use these, buy some of the brass caps with seals. They will insure no leaks, keep debris out of the valve and protect the threads. The plastic caps that come with the canisters are okay but the brass option is more secure.

I have been refilling disposable bottles for years with cheap neck fill adapters. This is a BIG upgrade. I will never buy another bottle of propane. I bought 4 of these, love them so much i bought 8 more! These are great, works woth the custom refill adapter, same brand. The vent release only works while filling, no risk of it venting any other time. You must use the custom filler and no other will work. There is a safety detent pin that overrides the bottles vent pin to the vent valve. There is still a safety pressure relief valve on the bottle. These are high quality and will be inherited by my grandkids some day. I bought magnetic stem protectors and carry case, thise are not included. They did come with good sturdy plastic caps. I never write long reviews, to do so on a propane bottle speaks volumes. These things can be topped of to your liking. They really hold a max volume of LPG. maximizing your time. I burn a lantern on max for 8 HOURS on 1 bottle. This has changed my camping style. I cannot go without these. If you disposable propane bottles see these and don't buy them your messing up. Buy them now.

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
