Faulty buckle

I've used it once or twice and have initial impressions
Size Bought:
6' 1"

Last year I bought the backpack. Since receiving it, I have gone on a total of two treks with it, not surpassing 100 miles altogether. During the second trek, at the end of the second day the left-hand shoulder strap’s buckle snapped and I was forced to make a filed repair and continue on. Besides that, the side straps are badly placed and do not allow access to the side pockets. There are way to many straps on this pack, and it is frustrating to cinch it after each packing. Furthermore its structure makes it difficult to place different items in it since the body of the pack is to narrow. Overall, the materials are good and the idea behind this pack was interesting but it is executed somewhat poorly.
