Query: Disappointed but heard back from company

I bought deluxe Best Friends grazing muzzles from a local store. After a month the hole at the end of the basket began to tear, and now it looks like a comma, not a period, and grows ever bigger.I did hear back from the company's president who offered to swap out my almost brand new muzzle for a new one, free of charge. As for the ever-widening opening in the basket of the muzzle, which allows the horse to eat more and more grass, it was explained to me by several people that it may just be the way my horse tears away at the grass. I am still disappointed that the muzzle hole didn't stay intact for more than 6 weeks, but perhaps it is one of those things where depending on the horse, muzzles don't last more than a few months.
