What sets this bag appart from others is its femininity. I have seen many wheeled cases... all of them "luggage looking" in construction... and couldn't bring myself to purchase one. I'm a woman, I have style, I don't want to be lumped with all the men but rather stand out on my own. This bag allows me to do that. It's made of nice quality leather, the stitching is strong, and it holds quite a bit. It's not for those who need to lug a ton, but my 15.4" laptop fits the sleeve (snug, but it does fit), there's room for a few files and my leather portfolio, and in the front area I carry a power cord, extra USB connector, and some basics like pens, extra discs, etc. The detachable wheels are a GREAT idea. It does take a few minutes to remove them and then conceal the open zippers, and it's not the most graceful task, so I'd recommend removing it prior to meeting your clients! That being said, those minor inconveniences are a small price to pay for the ability to relieve my neck and shoulder of the burdon of a briefcase.
I purchased the red and it's gorgeous. It's a show-stopping shade very similar to the color of lipstick the starlets wore in the 50's and 60's. I'd recommend looking at all of the colors directly on the McKlein website ([...]) because the interior and thread colors are sometimes ususual and obvious (such as what appears to be red thread with black leather, and orange thread with brown leather). The interiors also come in different colors (mine is orange). I found the McKlein representatives very helpful in answering any questions I had.
