The motion like it for various reasons very well: size -> small, quality -> stable connection -> easy mounting - is> practical and the most important thing, he still works very well. The function is unfortunately not self-evident, those like me who has had experience with other devices, which can perhaps confirm. The recognition itself and also the setting convinced me; therefore hereby my full recommendation.
Experience I have now with two devices, the first of which has been in operation for about 4 months. I plan to equip further rooms with this model.
