I've been using software and online tools for three decades and have to say in all that time I can count on one hand the amount of times I have come across something as instantly appealing. Not only is Endorsal a great idea in and of itself, but the implementation is absolutely superb. Not only are the basics well thought out, but the additional power-features take things to a whole level. It looks beautiful, and the workflow is perfect. I can understand why this is getting one of the highest ratings ever seen on Appsumo. If you have any kind of product that needs testimonials you are bonkers if you don't grab this whilst it is still available. If you don't you are going to regret it :-)
