I have used the coppers drops for two small batches and have been happy so far. The primedose seems a bit too expensive for me at twice the price of the coopers.
I also don't trust the reviews on Northern Brewer. Too many 4+ star reviews and I have read many bad reviews on the big mouth bubblers on other sites. I'm just wary.
whats the skinny on big mouth bubblers?
I have read about catastrophic failures with the glass. Some believe it is due to the large opening and lack of structural support that a normal carboy has. I have also read of micro cracks in brand new units.
With the plastic, I have read about warping of the opening, sagging, and poor seal. The seal I could deal with, warping and sagging I cannot.
I have basically read enough to make me spend the extra dough on speidels when I get around to upgrading. It's sad, I was excited for the plastic version.
