I'm going to go another route here so forgive me if I ruffle some "feathers". Regardless of who or how those arrows were fletched the ultimate responsibility for their failure, in this case, falls on the shooter.

Many people do what you did. Buy new arrows. Use some to practice with and set some aside for hunting thinking that a brand new arrow is something magical. This is a fallacy.

Not sounding too critical, but over my 40 years of bowhunting I never entered the woods with arrows in my quiver that I had not shot extensively, and in most cases all summer long or in most cases for several years. The only change I made to those arrows was to screw in the actual broadheads that I would hunt with and check to make sure they still flew well and hit where I aimed and maybe practiced an hour or so with them. Just prior to hunting I installed new blades and was ready to go.

Keep this in mind for your next venture and good luck.
