Would you use/ refer this Customer Success tool after visiting its landing page?

Hi, My friend (Stanford CS Master, McKinsey) and me (ex-PM at EventXtra-500 Startups B19, TechCrunch Disrupt Beijing Top 15) are recently building a Customer Success tool focus on troubleshooting. Website: http://www.usersavy.com It'd be great to hear: - Will you use it? - Will you refer it your friends/ colleagues? - How painful is troubleshooting in your Customer Success team? (1-10 most) - What's the most painful and frequent problem you faced in your CS team? It's my first time building own product so I look forward to hear advice from you all! Thanks a lot! :D
