I think it depends on your dog and how you will use it. I bought a good one on a really good sale. here is what I've found. It is good to use for traveling (to keep the dog in one place, and comfortable, don't know about safe.) It is good to crate a quiet dog with no desire to get out.. It is not good to contain an excited dog. I would not leave a dog unattended in one, or try to use it to keep a dog separated from another animal. so, in short, I think the only benefit to them would be how easy they are to carry, fold up and down, but what is the use if you can't feel a dog is secure in one? I only trust mine for car travel, or to use as a bed. all my dogs love the thing for some reason.
