I agree with the last two posters. Very inconsistent results, but in my experience, mostly way over carbed. I thought it was something wrong with my process, but I guess others are having the same problem, so that's good to know. I'll be continuing on with priming sugar since you have more control and there are some great calculators out there. That was the main reason I was using the carb drops because I was scared about calculating the priming sugar wrong, but as I've seen on here, it seems pretty easy, and like I said, you get more control over the results.
