Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Excellent option for beginners not wanting a cheap DIY solution
*by M***W on December 29, 2020*

Creating an epic high-tech aquascape can be expensive. When I first learned about the cost of entry for a Co2 set-up (yes, as a disclaimer I'm a beginner) I was pretty hesitant to jump in. I only have a 10-gallon tank, so I wanted to start by using the smaller paintball canister setup instead of a full size Co2 tank. After what felt like a bazillion hours of online research, I decided to go with this F-zone unit as it seemed like a nice balance of quality and price (kinda like the Goldie Lox concept not too cheaply made but not the crazy over the top kind.) It has been almost a month since I started using it and it's been pretty close to perfect so far. I did struggle a little when trying to get it set up. In my first attempt, I wasn't getting any pressure to register because I didn't screw on the provided adapter tight enough onto the Co2 tank. I was worried about going too far and breaking things, but I learned it would only work after I screwed it on as far as it would possibly go.) I figured this out upon trying it on a second Co2 canister but made a noob mistake in thinking it was broken when I removed it completely and didn't see the pressure go back to zero. A quick email to F-zone (they literally responded in less than an hour) helped me realize my error in logic. They informed me that pressure will get locked in the valve when you close it to remove it (a commonsense thing when you actually put any thought into it since the whole regulator is meant to control the pressure, duh. Silly me). Getting the bubble count that I wanted wasn’t hard to achieve with the sensitivity of the valve on the unit. Knowing what works best for your tank will take time and testing (mine was about 16 bubbles per 10 seconds), but I have seen no issues with it holding the count I set it to when putting it on a timer. When it first turns back on, though, I did notice the Co2 will take about 1-2 minutes to stabilize to the bubble count it was set to. My final Co2 set up (including this regulator) has been perfect for my needs. I have no regrets about this purchase. It’s not as cheap as the DIY set-ups but the quality and consistency are much better and worth the price difference. It cost me less than $250 for everything. I have a few non-essential items in my set-up so you might even get things closer to $200. Here is a list of all the items I use for anyone who is interested: • F-zone Co2 Proof Tubing • Generic Stop Valve (to stop water siphoning back up into the provided bubble counter) • Generic Stainless Steel U-shaped Tube Connector (to get up and over the rim of the tank as Co2 tubing is very rigid) • Zoo Med Mag Clip Suction Cup (much stronger than normal suction cups to hold the diffuser in place) • Neo in-tank diffuser (though, I will be trying an in-line diffuser for use with canister filters to reduce the “Sprite” water effect) • Jardli Drop Checker (the sphere-shaped one) w/ some Fluval CO2 Indicator Solution • AHRISE Smart Plug Power Strip (to put the lights and Co2 on an app-controlled timer) • and two filled JT Paintball 20 oz. Co2 Tanks (one serving as a back-up for when the other runs out so there is no gap in Co2)
