Bought two of these to refill atvs and a generator when camping. They work great once you know the trick. When I first filled an atv gas went everywhere. Found that's because I loosened the air inlet completely and gas poured out of it. The trick is to only loosen the inlet cap enough to let a little air in when filling, which creates a vacuum and keeps gas from coming out the inlet. Once I figured that out I filled atvs, the generator and even my SUV with ease.

This bottle adapter did the trick, I didn't want to have to carry a big 20 lbs LP gas tank when tailgating. This adapter allowed me to use the 1 lbs disposable tank for cooking on
my Sportsman's Series portable gas grill from Sam's ($99.98). I took two 1 lbs tanks, but only needed one as all we cooked was a bunch of hotdogs and sausages. Not everyone arrived at the same time so I had to stop and start grilling a few times for a total of about an hour and 15 min of grill time. When done I had about 1/4 of a 1 lbs tank left.
Note
If you don't finish the 1 lbs tank, I would recommend disconnecting the 1 lbs tank connected with this adapter to the grill with the grill lit and on high, as when the tank gets disconnected while off, a lot more gas escapes. When you disconnect the 1lbs tank while the grill is on, less gas escapes. Just remember to disconnect the tank far away from an open flame.

Works great.  Docked a star for lack of instruction on how to insert and adjust the screw with the provided Allen wrench.
A little more detail: The little piece of metal included (cylinder, perhaps 6mm by 1 mm diameter) is a screw, threaded all the way - the threads are very fine and hard to see. One end is hollow and this is where the wrench inserts. Using the Allen wrench, you insert the screw into the hole in the inside center of the bottom of the adapter. You use screw the screw in the right distance so that when you screw the adapter onto the gas canister, the central piece sticks up just above level with top of the adapter (not the rim, the center portion). If the screw is not screwed in far enough, when you screw the adapter on, gas will begin to escape. I presume if you screw it in too far, and the central button is then too low, you will not get gas when you try to fill your water bottles.

Way better putting these on the useless gas jugs you have to purchase now.  Makes it easier to poor out with.

Great product  smoothes out the rough idle and if you couple it with the right mods you'll see a gain off this product

This thing is great.  Made leveling our popup camper a lot faster.  I was able to pull into the site, slide this in and level the camper.  Didn't have to worry about putting leveling blocks down and then pulling the camper on to the blocks.  Great idea.  Unfortunately, after we used it one time, we sold our single axle camper and went into a double axle.

Very easy to use and accurate. I must have for road trippers and racers alike

Super useful. Ive been diagnosing cars all over the neighborhood. I got this because my check engine light came on and I drove it to my mechanic to get it diagnosed. Well...... This is really embarrassing but, my gas cap wasn't screwed on tight enough and that caused the check engine light to come on. Yeah.... I felt retarded! I bought this to diagnose my own car in the future so I wouldn't have to make a trip to the mechanic if I didn't have to. Works great with the free app on my iphone.

I really love this system. The main feature in my opinion is the automatic on and off feature that is made possible by the solenoid. Fit's very nice over my two existing 20oz paintball tanks.

This inexpensive tool saved me a trip to the shop.  Thought I my ERG valve was bad because of the age of my vehicle.  I was able to read the code which led me to simply replacing the gas cap. This allowed me to pass CA smog!  Highly recommended!

I bought these directly from the seller because with all I was buying from them it was actually less expensive with shipping and all.

I have only one real complaint about these spouts. They are long and do not have a bend or "crook" built in to them. So you have to have one hand on the spout to bend it in to the opening and one hand (arm in the case of a 5 gallon) on the can for tilting. This make it somewhat difficult to pour in in many cases, especially in to small engines.

Otherwise the product is as advertised. I bought both the regular and Hi-Flo versions along with vent assemblies for all my cans that didn't have them.

Update!: The Hi-Flo version of these spouts will not fit in the hole of a vehicle gas fill inlet. When pouring in to a vehicle gas inlet, you need to be able to insert the spot into the smaller hole or flapper hole a couple inches down from the top just like when you use a gas pump. If you don't, you either have to pour very slowly or you will gush fuel all over. The Hi-Flo version of this spout does not fit in the hole that a gas pump nozzle will so it's useless for vehicles.

If you have modern cans, they have eliminated the vent and built it in to the nozzle itself. While some designs of the new spouts are helpful like hooking the spout on to the gas tank opening and pushing to pour (this can reduce spillage in some cases), the brainiacs who came up with the safety standard ignored that you may be pouring in to a small gas tank or even transferring gas from a large to a small can. The vents allow you to control how you pour.

Some of the new can's spout designs are just stupid, some are not too bad. I keep some as is and have converted others so I have both options. I have at least 10 gas cans.

Good product. Shame on my state for not allowing these to be sold/shipped to me. It's my life and my gas, get out of my shed big government! Fortunately I had a way around this restriction of my freedom and can now manage my gas as I see fit like the grownup I am.

This 5 gallon poly gas can is awesome. It is a great value even at the cost Amazon is selling. The convenience is what gets me. I have a riding mower. I take off the gas tank cap, remove the cap from this gas can, and insert the spout into the gas tank opening. No drips. I repeat no drips. You push the button on the gas can to release the gas and it goes into the tank. Release the button when you want to stop. Simple. Again, no drips. The handle on the back really aids in lifting and pouring. The directions recommend to push the button before tilting the gas can to relieve pressure and that does help. This really is no spill. Great product. I recommend it.

Easy set-up and works like a charm. I love not being locked into the Sodastream CO2 monopoly since Primo uses standard threaded & valved 20 oz paintball tanks. Like Sodastream, you can swap online or at stores (Lowes, in Primo's case), or you can refill for ~$5 (or buy additional tanks) at many sporting goods, paintball, or welding supply dealers. Yes, doing that voids the warranty, but CO2 is CO2, people. I haven't tried the syrups yet, and am looking forward to being able to buy additional bottles, etc. For those that like it highly carbonated make sure to start with cold (ideally filtered) water, which can absorb more C02.

I have been using this for over a month now. I have at 2010 JK on 33s,  skyjacker lift with control arms, steel bumpers and tire carrier with 5th wheel, and most importantly a Volant CAI. Before I installed this I got 10.4 MPG on 87. I now get 11.4 on 87. Prior to the install my Volant CAI would sound raspy at WOT. Now with the TBS it sounds like a new CAI. Noticed better response on the throttle and it got rid of the raspy noise at WOT. Volant should include this in the price I paid for the CAI but that can't be left for a different review.

Overall, I am pretty happy with gaining a gallon in this tank and fixing up the raspiness at WOT. Definitely worth the price. No real "power" gain, but you can feel an improvement on the highway with gearing.

Now to buy a chip and some new gears!

The struggle continues...

I bought a CPO Beamer and wanted to clear any sludge out while it was fully warranted.  Sure enough I used this and needed the coils replaced.  That to me is a good thing because I want all the little stuff done while 100% covered.  Car is now running better than ever and I use about a cupful per tank of 93 octane.  One caveat is to be SURE you have a funnel and use it only for this product.  It is goopy stuff if spilled on paint.  Patience to let every drop drain in is required.

Great product. Works well and looks pretty flashy. Only issue I really had with it was the connector threads were a little loose and had a hard time tightening them with the alan wrench. Even with teflon tape I still had a leak between the connector and regulator until I finally found a regular wrench and tightened it to almost the point of stripping the threads.
Luckily I have a paintball adaptor screwed into it as well so I'll never have to mess with looseing and tightening the connections on the regulator again, will just have to screw a new tank into the adaptor.

Oh, one other thing, there aren't any directions, so make sure you research before you put together. You'll want to have the on/off valve 100% on when attaching a new tank or else you're going to have an impossible time with it and make sure you can screw it fast or else you'll lose a lot of your CO2.
