fairly solid, easy to install.

Is used by us as a replacement for the unfortunately no longer available Vormodell where the Tasttatur was connected by a thin cable to the cylinder. There (riding stable with a lot of dust, moisture and frost / heat) was worn out the rubber keyboard after 8 years of use in harsh environments.

In this follow-up model, the keyboard is solid, but not always react immediately on the first touch. But you geöhnt to it. It is positive that one for wireless connection something better can be reached and start the visual field, the keyboard, and it will not be shaken, as they no longer have to be mounted on the door slamming.
The disadvantage, however, is that you now have two sets of batteries needed (keyboard and cylinder). Remains to be seen how often the batteries need to be replaced (a daily dose of runf 50 closing operations)
And a major drawback is that no longer the closings are recorded (who, when the door is opened) - that was important to us for reasons of evidence.
