Since I my bathroom window still wanted to secure a little better and the window frame is relatively narrow installed, I had to for a narrow product decide. I chose ABUS, because I have had a good experience so far. The installation is relatively easy, should not be a problem even for inexperienced. In the ABUS range, it is one of the easiest auxiliary locks, for really vulnerable windows it is better to use a higher-quality window lock, because it has little bearing surface, for my purposes, it was enough but. One should anyway additionally protect the fishing side against up-and open levers. So as I said, to be recommended as a guaranteed minimum income, otherwise prefer higher number. The price is OK, specialist retailers wanted the double of me, by the way, there were these locks too Deutschmark times, the amount has remained the same, Unfortunately, now only in euros. ;-) Where I bought, there are the locks keyed alike, which means you can use all the locks with a key.
