I was expecting to see the widget on your site to be able to leave you feedback... lol
Looks like a crowded space, I can'f find you on google...at all... with all the keywords I can think of. I do find Usabilla everywhere though and a few others but they look Uber expensive... lol Ya know, when you can't find a price but you see a big contact us for a demo button... lol
Now I am curious, How do you go about finding customers in that space?
On the copy side, I would tend to agree with @rfctr that I sort of don't get what you are at a glance, especially if I come from visiting the others in that space. Usabila was the one I could get the easiest... because I was able to click on their widget and try it for my self... I was able to click on feedback, click on a part of the website... choose a little face icon and leave comments...
Maybe instead of copy, you should actually get users to try it? Then they would get it?
