I track all my comics in a different collector app and it still works great. I love that it stores the scans so that if there are any issues (or variants) without UPC codes or with incorrect UPC codes, I can easily resend the code to enter or correct them.
Also, works great when your Database computer is not on the same network!
Well worth the $ if you need or want barcode scanning.
