I've been using it since June and have had no issues, thought I'd switch to C&S when the 500gm discount died but as it was extended I am still using it.  Have had to cancel three or four times and most of the refunds are credited quicker than the 25 days, and often before the monthly bill is due.  My only complaint, if you can call it that, is that you can't rearrange the labels when you print, I use A4 label sheets and would prefer to be able to print more than one to a page or at least position the label so that I can reuse the rest of the sheet for the next label, but the interface doesn't cooperate on this point.
