As I read the reviews before buying, I immediately ordered two bridges and have these interconnected. That's wide enough for my rabbits and works beautifully. Workmanship, protruding nails or other, I could not tell. On the contrary, I have long been looking for such a possibility for my long-eared and finally found. I'm very satisfied! To the customer who holds this bridge for a waste of money, I can only say: Although rabbits can make air jumps, but nature has not provided specific jumps anatomically. The one forgets happy because always everything goes well. For a rabbit, the bridge over the cage edge guarantees constitute aid. I had a young animal that has broken his leg while jumping from the cottage. It was a strong, healthy animal, but by nature just a field and meadow animal. Therefore: I'd rather lose the mentioned ice and am pleased with the support for my rabbit. I recommend this bridge and should appear someone too narrow, then buy two. I did not regret it! On The Contrary!
