I can't believe the quality you get for the price on these things. I've had one for about 2 years and another for 1 year without any issues. My fiancé, who turned me onto them, has had hers for about 5 years and hasn't had any issues either. The only complaints I could possibly fathom is they don't come with a waterproof cover and the tripod attachment straps can get lost if your not careful because they're not sewn into the body (but are instead attached through sleeves).
I just whish they made a bigger one for my large format camera. I can only fit about 3 lenses (one mounted to the camera) with their lens boards in the bag if I'm also packing my 4x5 Speed Graphic, a dark cloth, plus 6 film holders. Not too bad, but
