Purchased from Costco with hand held scanner. Top of the line with link to PC and Quick Books. This is by far the worst product I have ever purchased. Z tape is nightmare and product does not have any support. PC features don't work at all. Error after error. Absolute nightmare compared to my old cash register. I don't know for 2 weeks now what my daily sales are. I will never buy anything else from Sharp. If I could rate this I would rate it a 0. Beware!
