What do you like best?
FastTony is the fastest-developing Facebook Ads tool, introducing new features like every week. It's no longer a "tool" but an ecosystem with plug-ins to Facebook, Instagram, many supporting Apps and even entire environments such as WordPress. I happen to be early adopter of them from time to time and have always had an excellent communication with the key Team - from the technical to the very CEO. Note that Daniel Kędzierski, the CEO is always on top of what's happening and he will not fall asleep without having all the questions answered. You will never have such a support from Facebook Ads Manager or Power Editor, let alone Catvertiser.com and it also means serious savings to your budget.
What do you dislike?
I hated when my trial period ended :D Naaah, it's a joke. There's nothing to be disliked, really :)
Recommendations to others considering the product
Please refer to my above responses, if you don't like spending too much on promo, and continue being as effective as with your current solutions such as BM, PE etc. Remember Facebook is not unveiling its full potential on the BM, they only have it over their API, where FastTony is seated and is shaking the best juices out of it.
What business problems are you solving with the product? What benefits have you realized?
I have a Social platform that's being fueled with Facebook Ads, Instagram and LinkedIn. Without FastTony we would be probably looking for an investor in order to pay for our promo spends. With FastTony though, we can optimize the cost so well, that we've stayed self-funded though the most critical moments.
