I like that it is an easy way to collect data from our customers without asking them for their personal information or requiring too much of my time in order get accurate results, especially with surveys where you might have 100+ responses! It's not as user friendly when compared against other survey tools out there (like SurveyMonkey).
The cost can be prohibitive at times if your business doesn't receive enough traffic/sales per month - so make sure this fits within budget before signing up :) We use trustspot primarily during onboarding processes & first impressions / reviews but we've also used some custom integrations using Zapier which has been very helpful over email marketing campaigns etc.
