I've had the kennel for 2 weeks, and used it several times at classes and for weekend travel. I purchased the largest size for  my golden retriever, so some of these comments may only apply to the large kennel. I am very pleased with the light weight of the kennel, and the ease with which it collapses and constructs. Find some of the zippers a little taut, so it will be interesting to see how they last over time.... they are heavy duty zippers so I am hoping that is okay. I haven't found a neat an tidy way to fold the kennel to carry it, so I sort of have to "hold" it collapsed. Its certainly miles better than my heavy wire crate.
