This software is very easy to use and it's also affordable. It has helped me to decrease our number of no shows at our events by about 20%. I have been using this product since they first launched in 2011 and have never had any problems. I can't think of anything that would make me not like this program. The customer service support is also amazing and helpful. We've used other event reminders systems but none have come close to the features offered here. I highly recommend this product. I am able to see when people are going to be late and give them a heads up if need be.
