The ABUS window handle is of higher quality than the old ones. He feels ergonomic and makes the whole door quality. It's fun to open the windows and doors now. After the purchase, I've noticed that in all the window handles fit only this one key. In theory, a burglar can buy the window handle, and then use the key on his victims. Nevertheless, one feels safer. As regards the protection of small children, they are naturally good. A push of the button is enough for closing. What bothers me personally but that they are still minimal move in the locked state.
