I only gave it 3 stars as I do not know how well it works yet. Hopefully I will be back to update it to 5. UPDATE: I've accumulated $10, still don't know what to do with it. They keep asking me to update my review.🤷 I guess I'll just put my new balances. $15.47.... 2022 many years later and I still have nothing to use this on. It just expires and goes away.
