Awful - no support and buggy
Bought this a few months back and started to use it this week for my web development agency.
So far, it's been mega buggy - not compatible with WordPress (when someone is logged in), as the WordPress black edit bar appears on top of their feedback bar.
If you leave a comment, the comments box has a background colour which is about 80px wide, and then the text overflows - which on a white background, means that the user typing the comment can't then read what they are typing, as it's white text on a white background.
Then when you try and view the comment in the portal, the comment either has no text in it at all - or it resizes it down to a point size you can't read as it's SO small.
Worst of all, I asked for their "premium support" - 2 days ago, and they haven't even replied yet.
All in all, I am going to ask for a refund as it's wasting my time.
