I like that it has everything you need to run your campaigns in one place! It's easy enough so even those who are not tech savvy can use this product effectively without any issues or problems arising from their inexperience with computers/technology etc..
There really isn't anything about filpacs itself which would make me dislike using them as they have been very helpful when setting up our new account (which was quite difficult due because of how many different options there were!). The only thing i do find somewhat annoying at times however - but nothing majorly negative; we've just come across some minor bugs here &there where things don't work properly ebcause certain features aren’t available yet within filters / search functionsetc.,but these haven't actually caused us too much trouble since most people tend to be more concerned by other aspects suchas fundraising rather than technical difficulties anyway :).
