First of all, I was looking for a shoulder bag type carrier for our small mini schnauzer, but saw this in the suggested items at bottom of the screen while reviewing the other type bags. I LOVE THIS! It was so simple to put together, comes compressed almost which was deceiving in the size but once you pop the sides out and zip it together it was so easy. One time when we placed in the car as the car seat, they forget to take the handle bar off so my little baby, although sitting on the padding provided was not very comfortable with the bars under her. I wish the padding was a bit thicker to more absorb the bars, but I also understand, the intent was to take the handle bars off before placing in the car. It would be very convenient if you were able to just place in with the handle bars still attached and it be comfortable for our little pets, but I understand there are limitations. It was SO EASY wheeling the carrier like luggage instead of fighting with the straps of a bag, and making our baby distressed. She easily got in and out once she understood it meant a car trip to somewhere! I love this product, we just purchased it for our last trip to the lake so haven't had time to fully use, but during those five days, I couldn't have been happier with the purchase! There are little zipper areas so that when she is riding in it, you can unzip so she pop her head out and still see what is going on and be a part of the family, but when she got tired, she just popped her head back down and dozed. Love, love, love this!I bought this for my cat. He is 18 pounds and fits pretty well inside. He can't stand up if it is used as a car seat, but he's not packed like a sardine.I love how much easier it is to tote him around and I feel much better that I can use it as a car seat.One problem I have. (Long winded but important!) When it sits as a carseat, there is a cushioned piece that goes on the bottom that you typically see in animal carriers. But when worn as a backpack, there are airholes where the pet is standing. They are kind of unnecessary since there are other air holes, and I worry Robi could get a foot stuck in it. Not to mention, they were REALLY irritating when Robi decided to pee while I was carrying him as a backpack.I wish the cushioned piece was curved at least so it sits under the pet in both directions the carrier can be used in. That way, there would be no chance of cat pee running down my back... Again.Hopefully this is something the company thinks about and can possibly create. Otherwise, I really love this product! Just... Make sure your pet does their business before heading out.Love it and price was just write our trip is in December and plan to take our fur baby with usThis was just what I needed with my cat growing from 12 lbs to 22 lbs lugging around him in a standard carrier was really a impossibility. Since he travels with every other week on long road trips and flights I needed something that would accommodate him while I maneuvered luggage. It was easy set up and anyone saying otherwise is not reading the very simple instructions or never zipped up a coat. I was really planning on Red but clicked the wrong button. It's very sturdy - OK the difficult parts. It will not fit under the Airplane seat with the wheels on and you do need to mash it down just slightly by about an inch or 2. Due to the hard sides it does not fall in on itself and my "Loki" like the other ones did. The wheels were great and it stayed well balanced. I was even able to attach it to the handle of my large bag so they could be rolled together. The shoulder straps are great for the plane boarding and deboarding. This is awesome, Roll, tote, shoulder, Backpack and even latch into a car safety belt. and store it easily.My Chihuahua, Ginabella, begs for me to take her with me when I go to work. If weather permits, I give in. I have to go through the subway system of New York City. She is a little over-weight and the previous hand-carrier was getting to be too difficult. This carrier makes it much easier. The only problem occurs when she moves around while I'm pulling it. That action tends to make control at that point difficult. The initial assembly may take a moment to figure out, but once done, there is no need to do it again. Other owners of small dogs have stopped me in the street to admire the carrier and ask where I got it.This is the best and prettiest dog carrier I could find available. It’s a stroller, car seat and carrier. Is very comfortable for Ava who is 4lbs because it doesn’t smash like the soft ones. It’s steady and she can walk around and stretch and sleep in. The pocket on top is where I keep her passport and vacines documents, also bowl for food and water, her leash and poop bags.Ava travels with me every month domestic and international, we’ve been to Disney, Europe, South America, Statue of Liberty lol you name it.Thank you for making such a good product for my fur baby :)So far great! Easy breezy to assemble, to get my cats in comfortably (one at a time - one weighs 16 pounds!), easy to roll. I love being able to seat belt them in. Everyone (including the vet) wanted to know about the carrier. The only thing I am a little worried about (I’ve just used it twice in one day to take each of my two cats to the vet) is that in disassembling the carrier for compact storage - the zippers on the two main components might be easy to break - if you’re not careful. At the ends where the zippers disengage - the zippers stick. So you have to be patient when taking the carrier apart at the zippers end - As I think it would be very easy to break the zipper.Nice idea, but will work better for smaller cats. My cats are average-10 and 12 pounds and are too big for this carrier. Like the fact that it can lay down and be a car safety pod, but no real way to transition to standing it on it's end to roll once it leaves the car. It's like putting the cat in the dryer until they get re-situated. Good idea, poor execution.
