No unnecessary buttons or distracting features. It does exactly what it was designed for: quickly collecting feedback from your customers, viewing their responses, analyzing them, and taking action on their wishes or concerns.
Even with my small user base (fewer than 100 current and former users), the product recommendations provide enough material for a dozen or so hypotheses.
I needed minimal input and effort from our side, they did handle everything on autopilot on their own, which is something I value. They sent regular detailed updates, and came back with results.
Would recommend them, especially if you have a large user base.
