Excellent regulator. Own two since 2019 and still work perfectly.
I don’t know how this has only 4.2 stars, it’s an excellent regulator that is so versatile and can be used on CGA320, paintball tanks, and all disposable 5/8 UNF CO2 cartridges. With an adapter you could also use it on 3/8 UNF disposables or even TR 21-4 (soda stream). My use has strictly been on paintball and cga320 as I feel disposables are a waste and way too expensive when I pay $20 for 10lbs of co2. This was my very first co2 regulator back in 2019 and it’s given me zero issues. The needle valve may not be as fine as more expensive needle valves, but it is perfectly serviceable. Easy enough to dial in where you want and more importantly it holds steady. I’ve even used this with a cheap wyia 3 way needle valve running a uns 60u, 60p, 45p no problems. You do need to use an extension to clear the regulator and the valve on a cga320. If you really don’t like the needle valve (although I assure you it’s perfectly fine) you can buy an inline needle valve for $20 and run it inline your co2 tubing. I have since buying this purchased a high end regulator from co2 art and the fzone pro dual stage regulator with expandable manifolds. You can run up to 6 separate tanks on the pro by adding more manifolds although I’ve only run 4. Also this regulator and the pro model are the exact same as the uns versions that costs much more money. They are the same, made in the same exact factory. The pro does have a better needle valve, but this one’s good as mentioned. I actually picked this regulator up a second time a few months ago as it went on sale and i enjoy my first one which still works perfect 7 years later. There is one small (potential) issue with this regulator and that’s the fact that the cable could be damaged the way it connects and rests. I never had an issue and i imagine a replacement cable would be as easy as emailing fzone as they are really an excellent company. I just took some heat sharing tubing and put two layers of heat shrink which provides strain relief. 7 years still good. Multiple house moves and all. This is one of the best regulators especially for the price and considering the wide versatility. Trust someone who’s got 5 regulators and even a citric acid/baking soda co2 generator I bought out of sheer curiosity.

Excellent, no-nonsense regulator!
I had this and a couple other regulators with two guages, but I ended up ordering more of this one. Build Quality: Great, the only compaint I have is that the insulation for the two wires that connect to the solenoid came off for one of my units. The unit still works flawlessly, but I'm afraid of pulling the wires loose. Connectivity: I have used it with a re-fillable 5lbs CO2 tank and a small 95g disposable cartridge and both usecases are solid. The supplied adapters and o-rings are super handy! Also used it in upright and sideways connection styles and both of them work great. Adjustment: This is the best part. Using this thing is simple, it just has one guage that shows you the output pressure. Most diffusers you use will have a threshold pressure (ie 'this stone needs 40psi before CO2 will get pushed through it' type stuff). Just rotate the big knob until the guage shows your desired output pressure. Then use the needle adjustment knob to dial in how much CO2 flow you want. I have some small nano tanks (2G - 5G) and they need very fine adjustment. This regulator is able to do it very well. The knob isn't super touchy and holds its tension very well. I have tried using a couple other regulators and wanted to break something when I used those because I just couldn't dial my settings in. This thing is a beauty! Aesthetics: Aawesome. I love the elegant look of this thing. It's small, easy to fit in any space, looks really nice and high quality. Won't topple small cylinders over etc. Absolutely love this thing to bits. I wish I could hoard10 of these just in case the supply runs out. The lack of internal pressure guage isn't really a big deal for me. I find that the second guage just adds bulk and isn't useful 99% percent of the time. If using a disposable cardridge, there isn't really much you can do about the internal pressure. If you've punctured the cartridge, it's gone. For re-usable/detachable tanks, if you know when starting out that there is enough CO2 there to use the tank, that's all the information you really need. Having that extra guage sitting there and looking like Mickey Mouse is good for an over-the-top steampunk look, but I don't find it to be a requirement. I'm really glad FZone made this thing that sacrifices the optional funcionality to provide a better product.

Great regulator and great customer service. I bought this regulator due to a lack of space in a cabinet housing the co2 tank. It can operate without adding any height onto my converted oxygen tank so its perfect. Customer service was great when I had an issue with the wire too.

It's my first CO2 regulator, so I was a bit skeptical about the purchase. I did a ton of research and eventually decided on this particular model. It's highly versatile - works with the "regular" CO2 cylinders (those with CGA320 fitting), paintball cylinders and disposable cylinders. I hooked it up to a 15 lbs CO2 cylinder with CGA320 fitting, rotated the fitting that connects to the bubble counter so it's vertical (took me a second to figure this out as it was not in the documentation), and hooked it up to the hose/diffuser - the entire process was easy and completed in mere minutes. It also came with the wrench to tighten the connection to the cylinder - that's a bonus. I connected the solenoid to a smart switch so it comes on and shuts off automatically. It's only been a couple of days, but it's been working nicely. The input and output pressure remained steady, and the product does seem to be built in a sturdy manner. The only thing missing is a gauge that shows the pre-regulated cylinder pressure (i.e. how much CO2 is left in the tank), but that's the only trade-off for a mini regulator. For the versatility, price and feature, I am quite happy with the purchase so far.

Easy to set up and works well. I’ve been using it for about a month. If it breaks I will update the review, but so far, so good. I like the size of the regulator as well. I recommend using bubble fluid and not water though for the bubble counter. Water evaporates too quickly.

This is my 1st regulator for aquarium. Did a lot of research and decided on this one. I read other reviews and can concur that it feels very solid. It has a good weight to it and materials look and feel strong. I like that it is a dual stage regulator. I filled the bubble counter with glycerin to avoid evaporation (which occurs if you fill it with water). It’s connected to a Vevor 5lb tank using the standard cg320 connector. No leaks. Solid and stable bubble count. No issues with the solenoid connector. I had read reviews stating that the cable connecter wasn’t solid. But this one feels solid; looks like they added a tie wrap and shrink wrap to solidify the connector. The needle valve is, of course, very sensitive when fine-tuning the amount of bubbles. I think this is just normal for any regulator. I have it dialled in nicely to the amount of CO2 desired. I am very happy with this purchase and would recommend it to anyone. I also am impressed with the customer service at Fzone. They quickly replied to some questions.

This is my second time ordering this regulator Positive: Getting the job done. -compact and versatile - dual stage, no co2 fluctuations -precise control knobs of pressure -precise bubble counter Negative: -No dual gauge, can't see how much co2 left for refill -back power inlet only small pinn and cable are fragile, need to manipulate with care. -last co2 does diffuseur the welding broke couldnt plug it back..
