On a normal basis, I walk 2+ miles to and from school through all sorts of weather. I used to carry my laptop in a messenger style bag with all my books and binders in another back pack, which was all good and well while I was at a community college, and not walking too far. Now that I am at MSU, and walk everywhere I figured it would be a good idea to get everything into one bag. The laptop I carry on a daily basis, is an ASUS G73, which is a hefty machine to carry, plus my books as well. I have never had a backpack support the weight so well. The beacon supports the weight in a way nothing else I have ever had even comes close to doing, and in that manner I am very pleased. I am also very please with the chest strap and rain cover which really come in handy. The only problem I have had, is within a month the bag started to fall apart, the bottom fell out, and the left strap was starting to rip. I contacted customer support, sent a few photos, and now I have another bag already on the way here. I have never had such a good experience with customer support from any company before. They really stand by their product, and I am pleased to say, that they have earned themselves a lifelong customer. From now on I will only buy Everki bags, I mean who can beat a life time warranty, on a product that is so superb.
