    Good sensor 433 MHz
    Good sensor. It looks better than others. But it is not a pair of sensors, it is one sensor and one magnet. The battery A23 is included. Connected to IP-camera Escam Keeper QF502 without any problems. Great product. Thanks for GearBest. You are the best! :)

    Гарний сенсор. Виглядає краще, ніж аналогічні. Але чомусь в описі вказано, що тут пара сенсорів. Насправді тут один сенсор і магніт до нього. Батарея у комплекті. Приєднав до камери Escam Keeper QF502 без будь-яких проблем. Спрацьовує добре. До речі, двосторонній скотч для кріплення теж у комплекті.

    Haven't used it yet, but the quality looks good so far. I plan to play with it using an Arduino + 433MHz receiver. Includes the 12V 23A battery which is nice since it's not easily available locally.
    No cons that I can think of at this point.
