I bought these this year and have been using them for about four months. Smart Lock Pro x 2 Fingerprint Authentication Pad x 1 I'm selling these because I'm upgrading to the new Ultra. I haven't dropped them, so I don't think there are any scratches. The double-sided tape is still attached. Please remove it with a sticker remover. Currently, there are no operational problems. The fingerprint authentication pad was always attached outside, so consider it a bonus. However, since these are used items, please understand that they are sold as-is, with no returns or claims.
