Works perfectly, the only "but", after remembering 15-20 prints refuses to remember more, although in the description promised 120. It flashes as if it remembers, but then these prints do not react.

Fast delivery, excellent packing. Everything came intact. The sensor is excellent, recognizes quickly, confidently. There is an adjustment of the time on the relay. I recommend to buy.

I order the second time, the first set everything works, the prints respond in 1-2 seconds, connected to the intercom ComMAX and the electromechanical lock works on Hurray.

In appearance, everything is as in the description, the sensor of the imprint is a metal case, I have not checked the work yet, as I will check the feedback.

The seller recommend the product came quickly all the Clas checked everything works put five stars.
