I was very impressed by the many positive reviews and have then decided after some searching for this cabinet locks because invisible and also for bonding. Due to the complicated installation way I did not understand and because of the comic form of adhesive parts for inside (do not know who has closets where to fit) I left the locks are only once. Now we were but that afterwards rooms but too much and we have brought back before. After several attempts, and the waste of a castle as a "test" whether it really fits, I have now attached to three cabinets locks. Now have the internal parts glued to the screws with power strips. Both parts have a good time for themselves. But except for one, keep the cabinet not to. With a very light pull them go on. This has now also managed our son. I then the big part again displaced, because I thought I had it maybe set too far down, but then the cabinet could no longer close, because the parts came together. I can not explain what the non-functioning is me. We have now yet so ugly glue things externally mounted, does not help. I can not recommend these backups anyway.
