This crate is very well-designed. It has multiple carrying handles on the crate, and two additional options on the included storage bag. There is a big storage pocket on the back of the crate itself where you can stash all those ribbons, leads, bait, and treats; a large holder for a big water bottle or thermos; and even a washable sherpa pad, although the pad is very thin and I will add another crate pad on top of it. I bought the 42" size for my puppy because he is a long-legged breed, and it allows him to stand up or stretch out. It's BIG! He would probably have been okay in a 36", so measure carefully and consider how you might use it. I intend to use this multiple places, including dog shows, dog sporting events, and when traveling, and his bestie could fit inside with him! I wanted it to be extra-spacious so he would be comfortable on the days he spends more time inside at an event. What I liked best about this 4-door model is all the options for cross-ventilation, since I live in the US Deep South and we have hot weather much of the year. When we use it outdoors, I will add a reflecting shade cover and use a cooling mat.The downside was the instructions. You're pretty much on your own, so I recommend doing what I didn't do and take pictures of each step or make detailed notes as you unbox your crate. As advertised, it was super-simple to set up--all it takes is snapping the 2 top struts together and sliding the strut cover over each, then zipping up the top. Note that the page of instructions talked about velcro straps to secure the solid door covers, but mine has only elastic loops and toggles. Taking your crate down is more complicated if you want everything to fit back together the way it came, and I couldn't find any instructions online to help with this. Be sure to unzip the top door/window before you fold it down, then release the struts. I learned that I had to fold down the end with the manufacturer's name on it first, which was counter-intuitive for me. The sides have to be folded in correctly before lowering the other end and snapping the clips to hold everything together. Once you have that figured out, the whole thing fits easily into the matching storage bag. The included handle options on the bag mean I can toss it over one shoulder and still hold a dog leash and carry other items all at one time, even though I am only barely over 5 feet tall. The whole thing will fit between my second-row seats and my Trans K-9 dog crate in my Subaru Ascent. If you don't want to deal with the bag, there are two different handle options on the crate itself.I bought the purple after observing the numbers of similar grey and brown crates lined up at our first dog show. It is a really nice, deep eggplant color. There is a clip if you plan to attach a crate tag. Be aware that you cannot ship your dog in a soft crate, and it would not provide much protection in the car in the event of an accident. I don't recommend using it for car travel. One thing to consider if you live in an area with lots of wind is that it may not stay in place when your dog is out of it, or if you have a very small dog. The crate weighs less than 20 pounds.The picture is of my 9-month-old pup after he voluntarily went into the crate to check it out--it didn't even require treats to coax him in! He even curled up in the back and took a little nap before coming back out in this photo.The crate seems a little sturdier than the ones some of my friends have, but it would definitely NOT be appropriate for a dog who scratches or chews when crated. For now, I won't leave him inside when a friend or I are not right there to be sure he doesn't scratch the mesh door/window flaps. I'm pretty sure he'll be okay on his own when he gets a little older. I would emphasize that he has been crate trained in wire crates since he was a few weeks old, he sleeps in a wire crate (his choice since he has finished teething), he eats in his crate, and he spends time crated if we are away from home someplace where he cannot accompany us--so he has no crate anxiety at all. I would recommend that you crate train your dog in a wire or metal crate first before expecting him to know how to behave in a soft crate. Therefore, I wouldn't recommend it for potty-training for most puppies. However, in a stressful situation like a dog show, sporting event, or trial, it does give your dog a nice, quiet place to de-stress from the craziness if needed. Some reviews noted that this crate is heavier than some other manufacturers' options, but I think that is a function of the sturdiness and the number of doors (since each door has both a mesh cover and a solid cover.
