Thought I'd give an update as to how the labels are holding up.
The labels are actually holding up better then I thought, they're still stuck on the bottles, kind of amazing with all the squeezing I do. They haven't smudged at all but they have faded a bit which doesn't bother me. The only real negative which I corrected is when you first stick them to the bottles, the ends sometimes don't seem to stick. To correct this I just wrapped the labels around a pen with the printing on the outside before sticking them to the bottles. Now I can't live without my label maker
