Hartz Honey Hole review for Retail Barcode Labels

I use this app to create price stickers for my store. I do not like having to repeatedly go through the process to attempt to make barcodes. Sometimes it works on the first try but typically I have to go through the process repeatedly, at least 5 times of clicking " create barcode" then navigate back to the product screen and do it again and again until it finally actually produces a barcode. Some times i have to repeat this process over 15 times to get one generated and I have also found that it often will generate a barcode that is already in use which I have no way of knowing that until the cashier rings up an item and flags it for multiple items being linked to the barcode. It is frustrating!
