Does the co2 pro buckets actually work?

Im thinking about adding more co2 to my space. I've seen various methods from ez co2 bags to co2 buckets. I'm leaning towards the pro co2 bucket. has anyone actually used any of these products? if so, what was your expierience? are they a waste of $. I'm trying to avoid pulling in outside air.

From my understanding they do not produce enough CO2, but I have not actually used one.

I got suckered into buying one for my first grow. It was the dumbest noob mistake I've ever made. Not only was it expensive; it was worthless. It only lasts for about 2 months tops and the "refil" is only a couple of bucks less. Don't waste your money.
