This is of extremely low quality.  They send tiny zip ties to hold it together.  Little plastic zipties!!! I put my dogs in, and within 1 hour, they had figured out how to bust through the zip ties.  The mesh, as they call it, can be easily bent, which the dogs did and escaped.  They had run out from our property and down the road. This situation could have ended up much worse than it did had I not been there to immediately see what happened.  Do not buy this contraption.  It is a horrible horrible design!!!!
