I love that it is very user friendly! You can add as many users you want to your account for free while you are in testing mode (it's called "preferred"!). It integrates well into our website without being too intrusive because they have an easy-to understand dashboard/admin panel which helps them keep track of everything they need. There were some glitches where certain features would just stop working or not function properly but this was resolved shortly after contacting their support team who got right back to me quickly. Definitely recommend trying out this software first before jumping ship if other solutions exist that do what you're looking for better. Integrates really well into my site - there isn't anything negative about integrating at all so far.
