- really buggy
- interface not clear (which you wouldn't expect from a UI/UX feedback app..)
- chrome extension is also buggy
- full page screenshots from the chrome extension don't always match the page
- hard to annotate
- sharing public projects doesn't show screenshots in the project
- I wouldn't share this with clients for feedback
- this app is not ready for prime time

Only managed to check it now, and it's too late for a refund, but would have surely got this refunded..
