I have long searched for and then decided on this box because I wanted to have a good transport box for 2 cats and I have let myself be guided by the comments. After unpacking I understand why a lot of comments on the contents had that the closures do not make strong impression. I can confirm it. I have it hooked to manual. They are very fragile and can not be removed. Due to the fact that the closures are made of very thin material, you can while trying to remove them not particularly draw. In practice, this means that a change is not simply possible. The fitting together according to the instructions did not make fun. The devices are not supplied carrying straps (not the case) are very difficult to mount because the holes are relatively small, so that the hooks for the gear loops do not fall out again. The worst came to the conclusion: the fifth shutter does not close. He goes from alone again, no matter what one does. He does not lock as the other. This means that it rises by itself again and slowly turn upward until it develops no more effect. It is very annoying and spoils the joy of a new thing, in this case, a new transport box for cats. The total box makes a cheap impression. My old, but unfortunately too little box works much more stable and high quality. At the door you have to look carefully, that really are both parts of the locking rods each in the holes provided. The accompanying description to another box is displayed. The one knows really only of electronics, where various types of equipment are summarized in a description. All in all I would have kept the box if the fifth closure would have worked. Buy I would not again. I had ordered for the second cat another box, since they must be in separate boxes for an upcoming surgery. Perhaps this met my expectations.
