I am in law school had been carrying my heavy books and laptop in a canvas backpack. It was heavy, somewhere around 30lbs, but I figure I'm a farm girl, I lug bales of hay so no big deal... and it worked fine...until it didn't. A few weeks ago, I went to sling my backpack over one shoulder but it didnt quite make it up, falling back down and pulling my arm backwards with it, tearing my tricep muscle. Sooo... needing to heal and not wanting to press my luck I decided to find a rolling bag to do the heavy lifting for me.I checked the usual big box retailers for something that would fit the bill but all I seemed to find were airplane carry-ons and were really ugly, manly, cheaply made with rickety handles or plasticky fabric, or were too small to hold my 17" laptop. I came back to Amazon and was pleasantly surprised to find this Vankean rolling laptop bag with this lovely pattern. It is subtly feminine with soft tones suitable for a mature college woman, business professional, or traveler.The capacity of this unit is fantastic. It easily holds my laptop, power cord, three 700-1000+ page textbooks, various folders, pens and other stationary items, cell phone and accessories, wallet, keys, two large water bottles, and my lunch bag! It's perfect for my needs! It could easily convert to a weekend travel bag or diaper bag as well. Not only does it have wheels, it also has two sturdy strap carrying handles if you should need to negotiate stairs or need to save space. The telescoping handle collapses down into its own zippered pouch tidily away. There are three main zippered sections, two of those have lots of pockets and places to stash specific stuff. It even came with a little luggage lock for your laptop section.Time will tell as to its durability with heavy daily use. I will update in a year or so, sooner if durability proves to be an issue. I dont think it will, though, because it seems very well made!
