Question Carbon doser question

I have the option of buying a used carbon doser regulator and 10lbs tank. Just wondering if anyone has any experience with this regulator or if I should keep looking? Had one I built awhile ago but had nothing but problems with cheap components and don't really want to go down that road again. Thanks

I've had my Carbon Doser from since April 2013 and it's worked flawlessly every day since. I have it hooked up to the pH controller they sell with it as well as the CO2 reactor to dissolve the CO2. I go through 20 lbs of CO2 about every 80 days in my 135gal. I have it set full blast so that when the pH drops 0.1 units from it's target it cuts of to deliver the CO2 back down 0.1 pH units really quickly. You just adjust the knob/valve to control the bubble size i.e. the other regulator dial/gauge that goes up to ~13psi I believe. That gauge is not really psi but rather back off on that number if you're CO2 is not fully dissolving before it's added to the tank or else you'll see / hear that slurry/burping large CO2 bubbles (this is wasting it).

I've been very pleased to say the least. I've not heard anything bad about them.
