We bought this window handles, because our 3 year son to slowly walked over to look not only out of the window, but busied herself well on anyone. As his room is on the 1st floor, had to be offered here stop. The handles were delivered quickly, the A / reconstruction lasted about 2 minutes per handle and is to make problems even for non-craftsmen. You make some quality impression and Parental Control sufficient. They can be in a position, either closed or tilted in, lock. Can you deal with a drill, it is no problem to drill a second hole for the locking pin. So then you have both options. One shortcoming there: with a larger force the lock does not hold and the holding plate rotates. But good for the price and our purposes that's perfectly fine. For the price actually 5, because of the instability as burglary protection only 4 stars.
