The ease of use makes this product really user friendly! I love it because its so quick - you don't have time wait around at stores anymore when trying out products especially with my young kids who seem easily influenced/bored!! You do not hear people asking each other what they put into there cart like we used too but now everyone just does asap :) It has made our life easier since going full self checkouts which was one less person working = more money saved :o). Also the staff members were very helpful & nice whenever i had questions about anything regarding how something worked etc.. There isn'y much dislike apart from having someone else's phone being able swipe your tags while yours sits off line somewhere lol. This definitely helps me spend quicker than always before where everything takes forever. As soon as all items scanned through then paid instantly after thats perfect! If anyone thinking of getting some great deals here be prepared though prices tend tbe high compared eto most places however if u shop regularly u will get alot back over paying higher price elsewhere ;) I love how simple it makes paying at self checkouts! The only thing i dislike about this product would be having your phone out while you shop but other than those two things its amazing!! Its so great because now there isn't any more lines when checking items off of an online cart like before with traditional cashier systems which was very annoying sometimes during busy times.
