I have used the premade patties and will use them again this bee-year. The bees like em. My buddy uses the dry mix and makes his own patties. Doesn't work miracles like ad's want you to think, but seems to help if they need it.
I use the brood builder which pretty much same thing but cheaper, Dadant bought megabee and they sell both. My bees seemed to ignore for a couple days then started taking it dry, i may try and make some patties from HFCS and HBH and see if they like that better
