I bought the Tanglefree Ultimate Blind Bag and have used it for about a season. Overall, I absolutely love the bag... the number of pockets, the features, the size, etc. On a trip to ND, the seam of one of the bottom corners ripped open (pic attached).
Once I noticed it, I called Tanglefree and talked with one of their reps (Ashley). She was a pleasure to talk to and work with. After getting her the info she needed, she told me that they were sending me another bag. Within a few business days, a new Ultimate Blind Bag showed up on my doorstep. Overall, I could not be happier and I would highly recommend the company (and the bag) to anyone.
