I find it nice that you don't have to scan anything, use a shopping cart or even move items from one place to another. Just grab it from the shelf, put in your backpack and go. Sure you have to scan your phone when you come in but you'd have to do that when you pay anyway. So, it's much more convenient, you'd never be embarrassed because you forgot to scan something or the scan didn't work properly. Security guards won't be profiling you as you walk around. I find it great. It provides value that less sophisticated solutions don't. So, I'd consider it well engineered.
