Really nice, no issues. I've been running this controller on a 24oz paintball tank I purchased on Amazon for about 10 days now. I filled my paintball tank with CO2 at a nearby Army/Navy/Survival type store for about $7. This is my first time running CO2 and I noticed two things which may explain why some folks seem to have problems adjusting the needle valve/bubble output of this unit...The first 8 days of operation I was using really short regular clear tubing, like less than 16" total, and when I turned the needle valve dial the tiniest bit, I saw immediate reaction to change in bubbles either increasing or decreasing depending on which direction I turned the valve. Two days ago my "CO2 proof tubing" delivered, so I swapped out my short crappy clear tubing with this nice co2 proof tubing that is about 6' long so I could rehome the paintball tank out of the way. Now when I turn the dial I have extremely delayed reaction to change in bubbles. Of course regardless the needle valve is very sensitive, so the smallest turn does make a change to bubbles, but now it's more difficult to adjust because the tubing is so long it just takes a while for the pressure change in the long length of tubing. YMMV however I'm pretty certain the folks complaining about delayed reaction (like 30-60sec) for bubbles to change after turning the dial are upset because they have long tubing.This is an excellent controller, the solonoid works well, and it truly is set it and forget it. Of course I check my bubble counter multiple times per day and it's stable. So far my HC carpet in only 10 days has grown significantly and pearls every day under Finnex 12" Planted+ which is probably classified as medium lighting on my 7g cube.

After trying two different small c02 cartridge systems (the kind that take 45 or 90 gram disposable cartridges), I decided to spend the $ for a real C02 regulator system for my 5 gallon heavily-planted nano (though it would work just as well in a larger tank.)The only drawback to using this paintball system is the initial start-up cost, but compared to those disposable cartridge systems, this is actually far more cost-effective over just a few months. Total set-up for this with all of the needed components was around $125. C02 disposable cartridge systems that I tried cost $50 (Ista WaterPlant) & $70 (Fluval) for the initial purchase, but I was going through a cartridge every few weeks at $10-15/pop, not to mention the cartridges that were completely wasted by leaky mini regulators and impossible-to-accurately-control valves. Filling my 20oz paintball C02 canister cost $3.50 at Sports Authority and will last for months. So it's actually far more cost-effective to pay for a good system like this up front than buy all those landfill-bound disposables.My Aquatek Mini worked flawlessly right out of the box. Gauges are easy to read, there is no leakage, and the control valve is smooth and easy to set at your desired bubble rate.Do be aware that in addition to the regulator, you also need to buy a paintball canister, Co2-compatible gas tubing, and a diffuser. This regulator came with a bubble counter that is working just fine for my application.The tank and regulator are small enough to tuck into the bookshelf that my tank sits on, so the equipment is hardly visible.

I decided to go with this regulator after reading the poor reviews of the smaller Fluval systems. It is a really simple device but the directions could have been a little more expansive. It is just a single page that did not expand on possible additions to the solenoid like a timer system. I have only been running to system a couple days, and the needle valve seems a little stiff and hard to turn, but when I got my flow rate to where I wanted it, I did not get any drift, which is important because I leave it on when I leave for work. Overall a good product for the price

Update: after 5 years my first unit as reviewed below is still running strong! Setting up a second planted aquarium now, ordered a new unit without a second thought and have it installed and running flawlessly again.Original review: I give it five stars for value to price, since, now that it works reliably for me, it really is a good product for what I paid. The needle valve is finicky and very hard to get right. I also learned through bad experience that the connection between regulator and tank really has to be wrench tight (I added plumber's tape to the fitting as well). But I really like the paintball CO2 tank convenience, really wanted it to work, and after a couple of false starts it's been working well on a 10 hours on, 14 hours off timer schedule (1 bubble per second) for about a month now.Additional info: 20 oz tank, bit faster than 1 bubble a second running 12 hours a day lasted me 3 months and one week...

This has worked for the first few months. Then one day I unplugged it as I don't have it on a timer. The CO2 kept going into the tank. I had and from then on turn on and off the needle valve to shut the CO2 off. Even now when you plug this in, you hear the click from the regulator solenoid. I am giving a 3 star only for the fact that I can still use this, though completely manual now.I am trying to find a means of fixing this issue, maybe the solenoid just need replacing or something. I cannot recommend buying this as I have read others have had this same issue. You would think after the years this product been on the market, Aquatek would have solved the issues with its products.update - dropped to 1 star. followed instructions on Aquatek site of blowing out the unit, this just made things worse. If this is how good any of Aquatek products are then I will never buy their products again. I sure did like the design of this unit though. But what a waste
