I'm the treasurer for a veteran's organization, and we do many fundraisers thru the year that require me to hand count a large amount of cash. I was a bit hesitant after seeing some reviewers that experienced "miscounts." But ordered this one anyway as the cost was more justifiable to me, compared to some of the more expensive units. So far my experience is the machine counts have always matched my hand counts. At this price point, I still need to sort my denominations, but it greatly simplifies counting large stacks of bills!
