Test Report

13 Window locks 10/2020

Stiftung Warentest tested 19 retrofit security devices for flat doors, windows, patio and balcony doors, including products from Abus, Burg-Wächter and Ikon (prices: 37 to 535 euros). Several window locks in the test did very well, but two were unsatisfactory. Of the six door locks in the test, only one scored very well. One cross bolt fails. It hardly keeps burglars out.
