These work wonderfully.  One thing i did notice is if you have cigars that are a bit dry (label moves easily) do not put these in direct contact with them, them may hydrate too quickly and crack the wrapper.  I try to gradually integrate my cigars (especially when receiving mail order) first in a tupper-dor (or cooler-dor) with lower humidity and build up to my 70% humi.  For my larger 350 stick humi, i use 8 of these at one time to maintain ~70%.
