Looked very promising so I paid the $39 to use this service, uploaded an image, and put in my card details. Then I got a 500 Error, was told I was a spam bot, and still got charged $39....which isn't ideal...
Great product, looks really easy to use and will provide web designers some valuable information. It would be interesting to see if it could also be used to gauge peoples emotions while they are viewing content as well.
I think it's extremely important to get feedback on your website as letting people say what they actually think about your offer / website is crucial. And 100 feedback in 24? Sounds really tempting! I'll probably give it a try
