So far so good.  I plan on using my bag to travel to Haiti on a medical mission trip.  I purchased it due to the great reviews and the price.  I look for to testing it on my trip.

My dream traveling backpack; my globetrotting luggage has been simplified.

I have an upcoming backpacking trip which I purchased this for. So far the quality for the bag seems great and it is also a decent thickness. I sat outside with it for a while when it was 65 degrees out and it was perfect. I'll update my review after my trip when the climate is a little colder.

Nice bag. Very roomy for my purposes. The only negative is the straps are a little spindly. I worry if I have a heavier load, that they may break at some point. I plan to use it when I travel and the extra items I would carry on would be too much for the straps.

I have not used this yet but it seems to be exactly what i wanted.  I was looking for a bag that would carry around the water bottles, local maps, camera, aairline tickets, passport and small local purchases that pockets just ccan't handle.  Particularly at airports, I wanred something that I could open easily with one zipper and have access to all travel documets.  This looks like it will do it all with room for 2 water bottles and all the other stuff.  It is not a backpack because it has just one shoulder support but it seems to fit comfortably either over one shoulder for low risk areas and also fits well for across the chest use.  I haven't tested the anti-theft steel cables and hope I never have the opportunity to see if they really work.

So far, so good.  I used it the other day and love that it is so lightweight.  Plus, there's room for my MacAir laptop and other things.  The only gripe I have is the chinese logo/company name, which is prominently displayed on the back.  Oh well.  Other than that, this pack will serve me well on my trip to Europe.

UPDATE:  I LOVE this bag!  It went on the plane with me and was wonderful as a purse/snack bag/place to keep everything you'll need on the plane trip.
This little daypack was the perfect "tool" for my trip.  I had it with me everywhere I went.  It is so lightweight, and yet incredibly strong.  Now that I'm home,
I use it when I'm riding my bike, so I can haul home groceries or whatever.  Great, great bag.

Though a different color than what's on the site, I figured this information would be useful considering everything but the color is the same.

UPDATE 15 JUNE 2016:
I took this bag from the USA to the cobblestone roads of Europe and it held up perfectly. This bag was my 7 day Plane, Train, Taxi, and Boat ease of travel saving grace. The wheels held up very well as well as the pully-arm. Though the arm seems a bit flimsy, it never broke on me and handled 10kg (22lbs) easily. I was able to fit in for the trip 5 t-shirts, 1 polo shirt, 3 pair long slacks (pants), extra pair of shoes, tablet, cables, 6 pair of underwear, and 6 pair of socks with extra space for a few gifts.

It fit into overhead bins easily for Delta, Norwegian Air, and Singapore Air as well as the bullet trains Eurostar and ICE. I'm very happy with this product.

Initial Thoughts:
This is a very decent piece of carry-on luggage that is literally within most airline specifications. All in all you shouldn't have any issues at all with this being a carry-on. I've used other bags where the plastic lining has shattered, it hasn't happened with this bag as of yet.

Specs:
Empty: Weighed 7lbs (3.18kg) and the dimensions were (as measured from the bottom of the lowest point of the wheel to the top of the handle) 22in x 14in x 10 1/4in  or (55cm x 35.5cm x 26cm)
Packing:
I was able to easily fit 3 shirts, 2 socks, sweatpants, a pair of shoes, 2 underwear, 10.1 in tablet, with space left over for another 2-3 days worth clothes. (See pictures)

Durability:
Wheels - Hard rubber composite material. They were able to handle cobblestone without issues.
Bag Cloth - Well put together. Very few initial frays that I cut off with scissors. No new frays since purchase and two weekend car trips.
It will handle being checked in fine, hopefully the baggage handlers are gentile enough.
[10 year warranty, I personally took a picture of the receipt and saved it to my cloud storage. Useful for when you want to swap out.]

No issues. A little big to fit inside a backpack. So far so good.

I have moved my camera equipment to the new backpack (Canon T3i, 28-80mm lens and 70-300mm lens, plus flash, chargers, batteries, etc.), but have not used it on a trip yet.  Based on what I see, however, I think it is going to be a great bag.  I like the way my equipment fits in the bag, the ease of access and the sturdy feel.  I have configured the dividers for quick access to the lens I have off of the camera - the space is sufficient to comfortably store the camera with the 70-300 mm lens installed. I am also able to slip a full-size HP 16.5" laptop in the back of the pack, and have a good bit of room in the top pocket.  The only thing I miss is a side pocket for a water bottle.

I hate checking bags, and this bag let's me travel easy for (so far) up to 5 nights at a time. It's slightly shorter than my previous canvas bag,  but it has some extra pockets, plus each side expands if needed, which I have not even needed to use. Inside pockets are handy for
popping in your phone, wallet, and passport when going thru TSA scanners. Bag feels floppier when NOT packed than my previous bag, but has not been an issue so far. All the zippers are nice and hefty. Inside material between the side pockets and central packing area seems pretty thin. Upside of that is it's breathable. Downside could be wearing out easier. Time will tell. Overall a good value back, good looking too. I'm definitely happy with my purchase.

So far they look awesome. The material is nice and light and won't take up any room in my luggage. I haven't used them yet but will be "living" out of a suitcase for 15 days on a road trip which is why I bought these to keep my clothes organized. If after the 15 days my opinion changes I will gladly update this.

On my last trip to the Middle East and Africa I quickly learned that carry-on rules are not the same everywhere and ended up having to check my carry-on twice. I don't like doing that because traveling on business I can't take the chance of my bag not being with me or trying to catch up with me. So this pack looks like it will be the right size to be able to take the amount of clothes I need. I'm lucky I get reimbursed for laundry when traveling so I'm not bound to needing a lot of clothing. I can survive with 2 pair of trousers and 3 shirts and some underwear. Get some merlino wool clothing for the actual travel.

[edit Nov 2016] I've been on a couple of business trips and have not had to check this bag in once. I have the Farpoint 40L for my clothes and the Osprey Comet backpack for my laptop and camera gear.  One thing I really like with this bag are the straps that tighten down. Easily compresses the bag by an inch or two making it look even smaller. I was even able to buy presents on the way home and put them in this bag along with the clothes I brought and still did not have to check it even on US and Canada regional jets.

The bag was exactly what I expected (after reading some of the reviews I was a bit concerned). I was looking for an alternative to my old beat up backpack for travel. It had more than enough room for my 13" laptop, Fire reader, travel documents, and enough space for odds and ends. The two zippered pockets are useless for anything but flat items (they'll hold my passport and ticket just fine).

I purchased separately a few zipper bags for chargers, cables, and various devices. I think I'm set for a ten day trip. I'm delighted with the bag. It looks good and seems like it will function just the way I needed. I'll update this review after my trip, positively or negatively.

So far so good. A little bulky but all that gear fits with room to spare. Hoping this bag lasts!

Looking forward to using it next week.  So far I like everything about this luggage.

Received in Sept 2017 - so far so good:  It is light, a nice grey color, really practical two outside pockets (one either side) and decent internal space.  I would love it if it were a touch bigger but it is nonetheless a great business bag for women who travel a lot.  I really like the shorter handles that keep it tight on my shoulder or hang on my forearm or the long strap to put across my body.
