This is an excellent tool to test your website, it allows you create different scenarios that can be used in testing of any web page or app with great ease! I have not found anything at this time which i dislike about it but there are some minor things like how long does each scenario take before its ready? It takes sometime until everything loads up fully so if we want multiple tests then sometimes they overlap one another making us spend more than necessary amount of times waiting around till all our pages load completely. We use attansees mainly as part of my job role where most oftenly am involved into creating user flows/scenarios using their tools (as mentioned above).
