В целом доволен, замок скрыт, функционал на месте. Доставка была быстрой, упаковано хорошо.

Качественный цинковый сплав, ощущается надежно. Для тех, кому нужен скрытый доп. замок — самое то. Рекомендую Cheng Bei.

Норм замок. Дизайн лаконичный, в интерьер вписался идеально. Работает четко, ключи не заедают.

Хороший замок, металл тяжелый, качественный. Единственное — пришлось немного повозиться с подгонкой под толщину двери, но в итоге всё ок.

Отличная штука! Поставил в спальню, снаружи вообще не видно. Собрал сам, врезка прошла гладко, теперь чувствую себя спокойнее.
