I have mainly been using this feature when I would like to restock my Amazon balance using a credit or debit card. I have not found the ability to gift Amazon credit through this feature though, so I have given it 1/5 stars from that perspective. I have found that it is relatively easy to use, but I do wish that there was an option to delete the card with one-click immediately after uploading credit, so I have given it 3/5 stars from that perspective. There is no "thickness" to a virtual restock of Amazon balance, so I have given it 1/5 stars from that perspective.
Rating: 2 stars
