I used it last year at an event, we had about 300 people attend and everyone was super happy with their experience! There were no problems that came up during our time using them. Great company, awesome service, professional staff and they are reasonably priced for most events or weddings. We will use RtM again this year as well to have another event in town. This is a great way of getting feedback from out guests! It's easy to get surveys done quickly while also keeping track of your guest count and RSVPs.
