I've been using this cash register for the past 2+ years. IMO it's well worth the money. If you're concerned about battery usage I think I've only changed the batteries twice and on more than one occasion I've forgot to turn it off. Not a problem because it times out and turns itself on standby. Mine has paid for itself. In the past during busy shows I would skip looking up and adding the taxes so my customers wouldn't have stand in line. I now collect tax on every sale. The report feature is nice too. You know exactly what you sold on CC, checks and cash sales (if you void out your mistakes). HTH
