I absolutely hate websites that allow users to spend time inputting information particularly contact information like emails only to tell them at the last step that they have to pay to get the end result. It's a really scummy thing to do. Why do websites even do this? Do they really think that someone will drop $200+ on a whim because they've sunk 1-2 minutes? It's ironic that they provide a service to analyze UX when theirs is pretty horrible. Also it says top companies use UX reviews. Are they actually using the product advertised here or ux reviews in general? Because the way it's worded makes me think the latter.
