Looking for the "penny!" - Finally not only backpack, not only trolley I discovered this model of Kipling. I've been years in the field of absolute Kiplingfan handbags and backpacks City and use the brand mainly due to its Resilient and their light weight. That was the first impression when I unpacked the Trolley: hardly dead weight compared to many other models. Who needs to carry many heavy books every day, will be very pleased about. The extendable handle is smooth and has good length. Also in the sinking, you do not jerk around, everything goes "like clockwork" .When climbing stairs are the padded back straps very pleasant and you can carry the trolley easier. The practicality remains to be seen, he first impression however is great!
