The UI is easy-to-use, has great customer experience flow as well as quick loading speed. It's free for merchants using its services. There are multiple ways of earning points - shopping activity, referrals (word by mouth). Some merchants do not have enough reach or don't want others know about them due to privacy concerns. We're solving our problem of engagement of our core audience that had turned off from giving us feedback after several years in operation by leveraging our own system vs other tools out there to provide more transparency for our users' spending habits. I like that it's easy for my staff members in our store, as well at home when we are out of town! They also have rewards programs which is great if you want your employees involved too!! You can't pick any dislikes really because they do what there suppose be doing very good job overall. Get all stores signed up so everyone benefits from this business. !
