I bought 2 of these bags about a month ago. They are holding up well even with my boy who always acts like he's starving (all 1250 lbs of him) I do think that the holes could be a bit smaller to slow down the horses further. My big boy is borderline Equine Metabolic Syndrome so slowing him down is really an effort.
Great bag. Reinforced and easy to load with hay and hang with 2 straps.
