The app works great. You get to customize how you want your claim code to be displayed (uppercase, lowercase, letters, numbers, etc). Only issue is if you are doing a large amount. It will do about 80% of them and then stop (usually at a rounded number). Example: 375 codes, only 300 will generate and the other 75 did not show up the following day, so I have to run it again for the last 75. Otherwise works great!
