This was very easy to assemble. The only negative thing I could say about it is that the inner liner seems to be a little bit too long. It doesn't prevent anything from working properly, it just makes it a little harder to zip up the front opening. The instructions are also missing clarification about whether that inner liner goes outside of the side opening mesh or inside. But in the company's defense, it does appear to be a bit of a logical conclusion once you look at it. The liner must sit outside of the mesh so that the entire inner shell is velvet lining and it holds back the mesh from intruding into the shell. I love that the top zips open to let my pet poke her head up. I have a Chiweenie and she is a bit long for this carrier, but if she sits it works perfectly. But that does mean that her head comes out of the shell, so having this opening is wonderful. I appreciate the pocket that sits in the back by the telescoping handle, but I'd much rather have had mesh for my pet to see out of. If the pet walks in straight, they would have to turn around inside the shell and unless you extend the sides, there's not enough room for her to do that. The sides can only be extended when the carrier is off the wheeled platform and sitting flat on the floor. Trying to put the carrier back on the wheels with the Velcro holders is impossible to do correctly with the pet sitting inside the carrier. But I suppose the weight of the pet would keep it in place for the most part even if the Velcro was not applied perfectly. I still love it regardless of the small points. I haven't really used it out and about town yet, so it could be that I will figure out common sense solutions to the Velcro issue. At this point, I think using it so that you take the pet on and off the wheels repeatedly would be an exercise in frustration. Make a choice and stick with that. I would highly recommend this! I purchased this because my dog jumped off the bed and hurt herself. While she heals, it causes
