The product has been very useful when it comes down creating branded walls of posts/images within our event space.
We are able to create an area where guests can share their photos as well as post other items they would like people see (e.g., stickers). This helps us get more engagement at each event we host! I have not found any issues yet but this could be because my team does most things manually so there isn't much room for error if something goes wrong haha!! However, everything works great once set up correctly - nothing major here either way! Definitely worth considering especially since its free through Facebook ads manager which makes sense given how large FB's network is compared to others out there.
