I loved them when they first came in. Then they started messing with the software. I have a grocery store near me that requires everything to be scanned with the build in scanner (no gun). And be placed on the belt to get weighed. That means cases of water, soda, anything else huge has to come out of the cart and put back every time.
It makes me not want to shop for large items there. And I’m faster than most employees that run checkout.
