I have an extensive music collection and finally getting around to cataloging it. When you have a stack of CDs and LPs (with barcodes) it becomes tiresome to type in barcodes. I can’t tell you how many times I typed the barcode wrong and had to do it again. Anyway, the scanner makes it easier, because you can do multiple items and it goes right to your collection. Instead of taking hours, now minutes! Easy setup instructions, easy to use and a time saver. A great add-on to the CLZ family.
