Very Impressed, Great Deal
Color: Black, Size: Large
Purchased this as a gift for my travel clients who are going to Greece and I am so glad I did! At $9.99, it is such a great deal! And I love that it has RFID blocking, as well as a Bluetooth tracker, just in case. I'm excited to hear feedback from them and hoping the bluetooth tracker actually works! But so far, very impressed.
