The carbonation drops are intended to be used in place of priming sugar in the bottle only. I don't know how the solid drops would distribute enough sugar throughout your bottling bucket to ensure proper carbonation in each bottle.
FWIW, I've used them for the small amounts of bottling I do with each batch (for gifts and for future comparison to different recipes). In the 12-16 oz bottles, I use one drop and in the larger 22 oz bottles, I use two per bottle with good results.
