With the doors of our white living room cabinet, this cabinet closure makes purely optical great as nice discreet. The operation is very easy for adults (my daughter has the system has not yet cracked): pressing in the middle up and down buttons at the same time pure and pulls out the right side variable to adjust the width of the door knobs. And here is the little fly in the ointment, which is why I also deducted a star: Although you can extend the width quite strong yet - but unfortunately the locker lock has in the basic position is still (at least for our cabinet) too much air, so that the shutter relatively loose. We have about a 1 cm narrower closure needed for this fits perfectly. If my daughter wants to open the doors, go to this about 1 cm. At the cabinet content they can not pushing so and the cabinet closure thus fulfills its purpose. But it just is not quite optimal, unfortunately. I attach later from me, how wide is the locker lock in the normal position. If yes to one or another certainly very interesting to know. Info follows.
