Ad hype, is at best interesting, at worst misleading in some cases. You will never hear of any test which did not come out the desired way. Just as the drug companies will never release a study which does not make their drug look great no other ad will reflect badly on a product. No way to make me think that the 21 is 40 times stronger than a NID. Just a hyped up test that came out the way they wanted it to.
I do not think that a NID is a 10,000-15,000 a year gun like many modern clay target guns. Might make it the first year, without major wear or problems, but not year after year. 10,000-15,000 shells is more shooting than most doubleguns get in a lifetime or several lifetimes. Back when I ate, slept, and breathed duck hunting, I did not shoot 10,000 shells in four years. And I killed a lot of birds and put a ton of time into hunting. But I could have shot a NID and handled all the shooting I ever did back then. The NID is up to task, parts may fail but the design is solid and durable.
