I bought this product to avoid wearing the job files I exercise partly at home and partly on site. I find this perfect model because big enough for a large amount of documents. In the small front pocket, there is storage space for the laptop battery + mouse + a big calculator, pens, which is very convenient. Then a large pocket holds a laptop (mine is old enough so heavy and big, although 15 '') and several folders (about an amount of 3 or 4 well-filled shirts. The second great pocket holds the equivalent of a botin plus docs and PC. I am delighted and I recommend this model, cheap and very good quality (I compared with other models and it is really ideal!) to the wheels, we'll see in time, but for now everything is moving. The telescopic handle looks a bit lightweight but strong hand anyway.
