After witnessing my granddaughters car seat succumbing to the abuses of air travel, finally pulled the trigger and purchased this for our return trip. Easy to use, durable fabric and smooth rolling wheels. Only thing missing is backpack- type straps but large loop strap on top easily slings over your shoulder as long as you don’t mind it bouncing up and down on your leg when exiting the terminal.We’ve only taken this on one trip, but it was well worth purchasing. Toddler car seats are just so big and bulky, so we needed an easy way to transport it in and out of the airport from the car. It’s a perfect fit for our Graco car seat, with room to spare in the bag so we can stuff a few random things (like the bag this case comes in) last minute. It was very sturdy, the wheels were reliable, and we could even link it to our rolling suitcases (not included). It made that part of our travel so much easier! We just checked it at the counter, so we didn’t need to lug the car seat far, but with a toddler in tow this case was so helpful.This is almost the perfect car seat cover luggage, however it is not sturdy at all. After returning to our destination, we noticed a pretty big rip on the side. Unfortunately since it’s not padded, this will most likely happen to others who buy it.I would say, buy the padded one, even if it costs more… the money spent on this is not worth it.I loved this for traveling with my baby: made it easy to transport all baby equipment needed. The only thing I wish the company change is adding wheels on the front and back.the good: the wheels are a game changer! it was super convenient to be able to zip the car seat in and wheel it through the airport instead of carrying the almost 50lb thing through the airport.what we would change: we wish it would've had backpack straps. the bag only comes with one shoulder strap, which we'll admit is a handy handle for when pulling the car seat on wheels through the airport, but otherwise is pretty useless. backpack straps would be a great addition, especially as a mom who often flys solo with my little one. sometimes you just don't have the hands and really need to be able to throw it on your back and go.the bad: the quality just isn't there. the bag ripped the very first flight we took. it ripped a big hole just above where the wheel base meets the fabric. And on the way back it ripped some more. I highly recommend IF you buy this bag, writing your info on the carseat directly just incase your bag shreds like it did for us!I was a little worried about my Joovy Kooper fitting, because although it's an "umbrella" stroller, it's a bit larger than most. No worries, though, the bag is roomy enough to fit the stroller - but I did have to remove the wheels to make it fit lengthwise (not an issue for me).The material is sturdy, and not too difficult to fold up and stick in my stroller's basket. The handlebars are great, although I am afraid to carry it using the shoulder strap because the clips that attach to the bag look like cheap plastic that will snap from the weight of the Joovy Kooper (my stoller is heavier than most umbella stroller, so it might not be an issue if you have a lighter stroller). I just took the shoulder strap off and only use the handlebars.One thing I was surprised by was the padding. I re-read the item description, and it says it has a padded end. I didn't notice it said that when I first ordered it. I assumed the entire bag was padded. It's not, just the flip top end of the strollerbag. It's good for those who have a stroller that has all it's wheels at one end when it's folded. The Joovy Kooper has wheels on both ends when it's folded. If your stroller folds down and has wheels on both ends, only the padded end will protect your wheels. You might want to take your wheels off and store them in the padded end. The padded end will do well protecting your wheels, but the rest of the bag isn't padded and your frame in the unpadded part can still get banged around. Although, if it was a fully padded bag, it probably wouldn't be as easy to fold up and store while not in use.I do wish the zipper went down lengthwise instead of around the top. But I knew that when I ordered it. It would be just little easier for my heavier stroller to have the bag open the other way. If you have a standard umbrella, the opening shouldn't bother you.One last thing, apparently it can look a little like a duffle bag, and if you are going to gatecheck your stroller at the airport, there's a small chance it will get mixed up with regular luggage and not be waiting for you when you exit the plane. I bought some red ducktape and put a strip on the bag, then wrote "gate check" in permanent marker on the ducktape. Not super pretty, but we use this primarily for airports, and it gets the attention of the airline employees.Overall, it does it's job, and has held up well. Joovy makes a stroller bag specifically for the Kooper, but it's almost double the cost of this. I would choose this over the Joovy bag anyday. It's sturdy and perfect for the price!We were able to fit a front-facing AND a rear-facing car seat in this bag. We put the infant seat base in one of the checked bags... The bag we purchased had wheels, which allowed us to create a rolling luggage train. I won't say it was easy to roll all the luggage and two littles, per se. But it was easier than not having one, or having lots of stuff without wheels. I saw another family with a bag minus wheels and it definitely looked to be more of a struggle.We heard of several horror stories of airlines/baggage companies trashing child seats, so we bought this for a flight to the US. The seat (group 1) fits well and is held in place with an inner strap. There's plenty of space in side to stuff blankets, push chair covers, jackets etc. The wheels are pretty good, it's not the easiest thing to wheel through a busy airport due to the width and low centre of gravity (it tries to tip back upright unless lent over far enough). So it's maybe easier to load this onto a luggage trolley for long walks. On our return flight it seems like this bag fell off the baggage truck or got dragged across tarmac/a hard surface, because there was a HUGE scuff down the front which went through the (thick) cordura material in one place, and meant the seat was slightly scratched on a plastic panel and the seat fabric took a slight nick, which we sewed up. But without this bag I hate to think what state the seat would've been in - trashed cover & possibly broken plastic parts. A bit of duct tape sorted out the hole fine. It's not padded, so big impacts could still damage the structure of the seat, but it means the bag isn't too bulky if you need to fold it away in the boot.This is a great bag, it fit our booster seat and infant car seat together on a long haul flight from London to Sydney. It's not padded but the material is strong and it's well made. The bag and seats were intact on arrival and it was easy to carry. Ask your airline to check the seats as large baggage so they sit on top in the hold. Also as a side this bag fits Baby Jogger City Mini with wheels removed.We bought this carrier to transport our grandson's car seat while holidaying in Dubai as we did not have a car and were using taxis. It was considerably cheaper than the child seat cart on wheels. The whole thing is cumbersome because it covers a cumbersome article, but it was easy to wheel. The zips take a padlock so we were happy to leave it in lockers or 'trolley storage' at the malls. The shoulder strap is useful for carrying it up stairs. Overall it worked well for us. Obviously it acted as a travel cover for flying.This bag is huge - fitted in our Cybex Cloud car seat with tons of room to spare for nappies, clothes and other soft items which we used to provide some padding. Given 4 stars just because it would be good if the bag had some of its own padding. Liked the fact you could carry on the shoulder and it fitted around the body. Think this style of straps is also better for baggage handling. Material seems pretty strong and zips allow for padlocking. Seat was checked in via the special baggage area and travelled to Greece and back with no damage.Very easy to use and carry around. Fabric is strong and durable. My carseat is a bit heavy and this bag is not showing any signs of weakness.
