Update after 18 months: The bag is still going strong. I thought it would only last maybe 6 months but I am happy that I am wrong. I would say that the wheels have normal wear and tear, the handle does not move as smoothly, and the bottom is scratched up pretty good. But nothing is exposed and all the stitches held up. I have not been especially careful with it either. Just normal use and I didn't think much about caring for it. I usually carry about 15~30 lbs of stuff (laptops, pens, files) with me so I feel that I am putting it up to the test. For $40 bucks, you can't go wrong with this bag. I expect it to last another 6~12 months easily.------------------------------------------------------------------------Original Review:Order it Wednesday night and was at my door before noon on Friday. Amazon, you did it again!So a little bit of background info. I am more or less a traveling salesperson. Besides a 16' laptop, I also carry a secondary screen that's about the same size and just as heavy. Padfolio for notes, give away pens, my files, client files and basically bring my office with me. I hurt my shoulder so using my shoulder carry bag was starting to be really painful. I needed something that I can wheel around while my shoulder rest. I figured that at this price, this is disposable if it ends up to be a crap bag. So far, first impressions are positive.--- Overall Size ---It's just a bit thicker than my normal shoulder carry bag and just a bit taller. I say the empty weight is about 3~5 lbs and it's pretty much in line with a shoulder carry--- Storage Space ---Roomy. The first section (the small front pouch) can be opened pretty wide. you can see that in the pictures. I used a dollar bill so you can get some perspective. However, the little divider sections in the pouch are kind of a joke. I wish they would have made less section and make the pockets in there bigger.The midsection has a dedicated space for a laptop. Fit my 16-inch laptop and additional screen fine. Nice touch by adding padding at the bottom of that portion. I think it will offer some minor protection if you drop it a little. DIdn't do a drop test tough. There is additional space for my padfolio and files right next to the laptop section. It's pretty big. However, it shares space with the 3rd section of the bag. See picturesThe third section is where the handle is located. I took a picture on the top of that section when the handle has been retracted and zipped. You can see it bulging quite a bit. Kind of weird to look at. But I don't expect to ever put the handle away so it's not a big deal. But just wanted to point it out. I need this to function, not to look pristine. There is some additional space here but the funny part is that the divider "wall" between sections 2 & 3 is not sowed all the way to the bottom. So if you place something small in there, it could easily be rolled to section 2 of the bag. Not sure why they designed it this way. But not a deal-breaker for me since I plan to keep folders in that section. But if you carry a lot of small parts and need to keep organized, I would put them in ziplock bags beforehand.--- Mechanics & Material---Solid. The outer shell seems sturdy, wheels roll fine and the handle is nice. As for the handle, when pulled out at full length, it comes up to my belly button and I'm a bit over 5'8. Wheeling it was quite comfortable. Haven't load it up completely yet but the dry runs feel decent. The wheels do take up a very small amount of space in section 3 of the bag. However, your contents are protected by a piece of hard plastic between the wheel and the bag so I don't expect any damage to your things. There is just a thin fabric between the bag and the handle arm that extends inside the bag to the bottom. I would watch it if you are going to carry delicate items.Lastly, I would say the price. At $35 bucks, I consider this bag to be disposable. Not that I have $35 dollars to throw down the drain but I feel that it is offering quite a bit of value. I was concern about other reviewing talking about the wheel not lasting as long. However, since my trips are mostly around parking lots and office buildings, I figured that I can take that chance. I will update if the wheel fails for the light amount to "towing" I would be doing. That would be a pretty major fail if it can survive trips around a parking lot. Time will tell.
