i think, if you have problems with, say bandaids, you are more likely to have problems with reactions.
I dont think it is extremely common, and each brand is made slightly different, so most people seem to have luck with at least one or two of them.
If you have irriation you can use powders and such on the skin to keep the sticky from your skin, although it shortens wear time.
I think there are ways around pretty much any of the problems.
