  2. Customer

    Quality is not good. Tested 2 TM keys, one reads perfect, another sometimes reads all zeros, or internal TM code (unstable chip), I had same problem with another china clone of original dallas button (unstable reading). As i see, quality of this devices not good/stable.

    I took because of the multi-colored coloring, it is convenient when on a bunch of several keys, since, all that is sold around me in offline-only black, overwrite successfully.
