I bought this one as it seemed to be the only way to carry about the vast Dell laptop I was using at the time.
It should be a good bag, but it's let down by poor quality in certain areas.
1. The structural fabric around the top handle has torn apart, unable to cope with the loads I carry I suppose, but the fact is that there is no webbing going down from the handle to transfer the strain down to the base or other parts of the shell. This means the handle just pulls the top of the bag to bits.
2. The front of the bag loses its shape quite quickly, which means its actually difficult to use all these different pockets, the front just turns into a mess of zips and material and you can't find anything.
3. The wheels are small and there is no clearance at the bottom of the trolley, some rubbing strip at the bottom frays and falls off within a week (see other reviews). If you only go through posh airports with smooth floors, you'll be fine, but I go to some very underdeveloped places and need to hump it down rocky pavements. The bag does not fare well!
I tried to talk to Kensington about the issue of the handle coming away, as that was not good and they need to know their design needs a simple modification. I got bounced around by email and telephone between people who all saw it as someone elses problem, until eventually I got bored and decided Kensington weren't going to listen to feedback and improve the product.
I paid a lot for the thing, but it's only slightly better than a £20 thing I bought on the high street last week. So I'm knocking an extra star off for charging a premium price for a product that isn't.
