Never had a problem. I always buy the cheap as market / petrol station / cheapest in the bike shop job. I quite often just buy a pack of patches as I have vulcanizing solution left over. Last set of patches I bought was actually one pig patch 4 - 5" square and you just cut the size patch you want. You can also cut up old inner tubes and use as patches. Tend not to bother with that though.
