Can I write a review without trying them?
"I’ve considered carbonation drops for a long while, but have never used them. Why? Because each beer style requires its own personalised volumes of CO2. Just look at the instructions with these: 1 tablet for 350ml and 2 for 750ml. Does that sound right? As I am using a basic pail type fermenter, the idea of adding a priming mass to the wort at the end is untenable due to to oxygen ingress, individual sugar volume priming per bottle is boring and difficult to measure accurately. There has to be a better way and there is. I was pondering this issue and came up with a solution that is probably as old as the hills - calculate the weight of sugar to give required CO2 volume and then add water to make a syrup to an easily divisible final volume to squirt a measured dose into each bottle. These carbonation drops lack the accuracy I demand."
