I have been using this with one cartridge per liter, and have been having some problems. First, after emptying contents of CO2 cartridge too much gas breaks free from seal on the lid, actually popping (but not breaking, as it retains its shape...

The first time I used the Mastrad it distorted the seal & gas escaped. I discovered that I hadn't screwed the cap on all the way. The seal should not be visible when it is tightened & actually continues to rotate 1-2 more times before it is truly sealed. Then before i put the cartridge on I press the release valve in go make sure it is not stuck. Make sure not to cross thread the cartridge holder. After gassing I leave the cartridge in place, shake the canister & put it in the fridge for several hours. When ready don't try to open it until you press the pressure release valve until no more gas escapes. Then open the lid & replace it with the storage cap. If this doesn't help then I suggest you contact Mastrad. Oh yeah, use the white funnel provided to fill & only fill until the liquid touches the bottom of the funnel.

I had no such issue but did have one cartridge that leaked slightly. I contacted the seller and had a great response almost immediately. I'd recommend reaching out directly to the seller. You may simply have a bad chip.

Put a drop of oil on the tip of the cartridge. Insert into the gun(?) then tighten the screw until it just touches the cartridge (you will feel the resistance). Then turn the screw hard an don't stop turning until its fully seated. I get e little hiss momentarily but it seats just find. I've used probably 30 of my 100 cartridges with no problems. Good value and performs great in my CO2 BB pistol. Hope this helps...AO

Our local microbreweries won't fill it. What we have been doing is filling growlers and transferring the beer after sanitizing, no need to add sugar. We are using this with a mini kegorator, with the CO2 cartridge it will last a good month, or until the beer runs out (whichever occurs first).

You want to make sure the cap is sealed tightly before putting the cartridge into the container and screwing it on. If this is what you are doing and your cartridge is leaking, I would say that yes, it is defective.

I haven't had any problems with mine. It has been flawless since I got it. Would buy another in a heartbeat. Does everything I ask of it. If there is a problem I'd have to say it uses a lot of gas. Other than that it's great.

Makes a small amount of noise when the co2 goes in, I think the standard cartridges are much smaller than the one you have, should not drive your dog crazy any more

Loosen the screw on the bottom of the butt and slip co2 cartridge in and the tighen screw until snug. Test fir e several times to see if o.k.. It might need several more turns. Unthreaded cartridges are preferred.

my son bought this and he said that he liked it. But to me co2 is not as reliable as a pump action. if the seals are bad your c02 will leak out then you are stuck replacing it.

Hi Terrecial,One cartridge will make one container of soda. You have to use a different cartridge each time you make soda. I hope this has answered your question. Feel free to ask any more questions regarding the cartridges.

The cartridge has to stay in the gun after it's installed. Otherwise, all of the gas will escape if it's removed. You can extend the useful life of the cartridge after it's installed in the gun by applying a light coating of pellet gun oil on the end and sides of the cartridge cap(the part that gets pierced) before installing it. This helps to prevent any CO2 from leaking out when the gun is not in use. In my experience, cartridges have lost very little CO2(if any at all) for as long as 6 months or more when I've done this on my Crosman BB pistol.

That is the best way I know. Trying to pinch off the tube, or pulling out and raising the other end could result in some spilled gas -- danger! But this hasn't been an issue for me. This product works well as long as you are careful pulling out the correct end of the tube when you have enough fuel. It just takes a little thought the first time.

I have had it for maybe 2 years now if I pop a co2 cartridge in it, it will shoot fine but I don't shoot it that often just for the record and the co2 runs out progressively so your shots become less and less accurate as you shoot

I have not had that experience yet...though I did have the plunger on the bottom of the cone that holds the permanent filter fail to stay open. The filter was full to the top with water and some of it went into the reservoir. Would it be possible to buy a can of compressed air and blow it out?

I have kept it stable for several years in my freezer. I think the problem with this producer is the hole they have in the bottle cap. The active gases can escape.

I have had know problems with the co2. Like all co2 guns when you first put it in there is that brief second of co2 leak but the faster you are at putting it in the better.

I would suggest writing to the manufacturer. Depending on when you bought it they may replace it.One common problem is that people don't tighten the set-screw enough when they install the CO2 cartridge.
