Very good construction easy to assemble. The water container it has is small so I don't think it's useful. For my 10 kg dog, the size is good. Keep in mind, however, that the dimensions they provide are external and not the clean interior, so you should consider it according to the size of the dog. It is also good if there is a leash included for easier transportation.

Very good construction, durable and sturdy. However, a 25 kg dog will need a slightly larger crate. Up to 20 kg is okay. Also, for a car, I would recommend a crate with a side door.

The plastic ones look good. I recently got it for transporting it in the summer. It did its job properly in the car without letting the hairs float. So we are happy, as well as the dog, since it didn't struggle to stay upright. Its use was minimal. It went in the car once and came out once. It wasn't carried by the handles for measurements. Its assembly is done with plastic clips and screws (which are screwed into plastic holes). For this specific use, I would recommend it to a friend. I should note that I have never had a transport cage before, so I have no point of comparison.
