Does Anyone Prefer Sainsburys Scanner App to the Gun Things?

Forget it the App is very random and temperamental on your phone, it's slow, loses connection instore, doesn't recognise some products, sometimes fails to add your item to the list , and can be temperamental at checkout, also staff seem confused about what to do if you get the random security check at the tills. My advice stick with the Instore handheld scanner if you can .

I like flesh and blood people at tills.

Iv not tried either. I wonder how many checks they do.
