These giftcards redeem without any issue once you have another payment option created in your account. The cards worked perfectly fine for payment on the profile they were credited to. It provides great peace of mind to know that there's a ride home when needed!
As a couple, it seemed a great idea to load up on these on one account and share them through the family profile we selected (rather than divvy the cards up and potentially have small, unusable, balances on each account.) We tried this out and it didn't work. Instead the credit card was charged without any notification, or receipt issued. When we contacted Uber customer support, it took many exchanges before they eventually told me that "gift cards cannot be used towards trips taken with UberRUSH and Family Profiles." I couldn't find any information on the purchase, or redemption, pages that mention these restrictions clearly.. instead, it's buried in the Terms & conditions which, I admit, I didn't read before the purchase.
I really wish this information was included on the product page with their legal disclaimer or feature description.
The Gift Card cannot be redeemed for UberRUSH, or used with family profiles or university campus cards, or for scheduled rides.
