I am pleased with the product though I found it a little bit cumbersome to put together and did find that some of the peices did not want to go together as they should.  However, reading some of the other comments by previous buyers led me to use plastic ties which re-enforced the cages making them even and sound.  The cages will suit the purpose needed and will give the cats more room and exercise where the regular caging systems do not.  The cages are for use in an animal adoption facility.
