Review on Thetis Two Factory Authentication Protection Compatible by Joe Taniguchi

Works as advertised. Pairing was quick but the passcode is printed on the back, I could write it down somewhere and erase it for security. It's quite strong and durable, but the black finish seems prone to scratches and abrasions (see pics), deducting 1 star for that. The pictures were taken about 1 month after I kept them in my bag with no key on the keychain (wireless keychain only). When you attach this to your keychain it looks gross. Overall it works great and does what I need it to, I'm not too concerned about scratches but it would have been nice if it was coated with a harder finish. Although it feels like it should last a long time.
