I am real happy with it. It is convenient and stores in a real small space. It is nice that it pops up to take outside to the yard, so that my little dog can sit with me and not get out. I like that there is a lid on it, so my dog does not get too much sun. It was a good investment. Even though the bottom isn't secure, it is fine with me. I use it with for a small dog. I waited about a month an a half to get a from the pet store and gave up on them. I got it from your company instantly.
