I looked at this bag long and hard before buying it. In short...I love it. The design is very well thought out, although I have not used it much yet, i suspect the durability will be high, if there is one thing I have a concern about, it is the zippers, when the bag cover is open all the way, it does not zip shut as easy as I would like. I give this bag a full five stars. last thing, customer service is strong.
