I like that they have an excellent support team who are always willing to help even after hours! The tool is very intuitive which makes creating surveys or polls quick & simple. Sometimes there can be issues with formatting but this has been resolved quickly when contacted by their customer service department - usually within minutes of contacting them through live chat/email etc. We use interact as part our PPC campaign so we need something relatively user friendly in order to get people engaged enough to click-through from Google adsense (which typically only gets around 2 clicks per person). This lets us target specific questions about products / services being offered via Adwords campaigns - helping to improve conversion rates significantly compared to other tools available out there at similar price points.
