It took me forever to choose which of these I wanted. Seriously, it took me about 4 months! I had such a hard time choosing because there were so many mixed reviews on each one and there are about 25, or more, different styles, sizes and brands. So many reviews of torn fabrics and broken zippers and they scared me. Plus, some of the prices seemed outrageous. I finally settled on this one becausebthe orce was fair, the size was decent and the reviews seemed pretty good. I am very satisfied! Now, we’ve only had it for about a week and our 10lb chihuahua has only used it twice so we’ll see how the fabric and zippers hold up. So far though, it’s fantastic. It’s actually larger than I expected. I’m a 5’1 woman and I can crawl into and fit in it, laying down and curled up, easily. Our girl has plenty of room to play, roll around and even jump a little. Her bed, food and lots of toys fit in it comfortably. It is super easy to open and fold back up. It just pops right open and the top and bottoms easily zip on and takes less than a minute to fold back up and easily stores right back in its bag. Very convenient for travel!
