For short distances and small birds

the box is sufficient. We have 2 budgies to and from the vet so transported (about 10 minutes each). That was just, and this is anyway already very tight for the two birds. A disadvantage is the small (from top-to-use duck) opening because our birds partout not purely wanted and then it already is a very nice difficult undertaking, there to get a bird against his will inside.

Conclusion: Suitable for a small bird to short transport, borderline for two small birds, for larger birds (greater than budgerigars) and / or longer transports not recommended.

Price / Performance: good
