I remember wanting a Night Guard shortly after they stopped making them. It was a winner design. Can't understand why they discontinued it.
The answer is simple, it wasn't a winning design and it didn't sell well enough to remain in production
Didn't sell likely for two reasons: 1) ineffective advertising (I hadn't heard of them till they had already stopped production, and I'm fairly tuned into to the gun world), and 2) they didn't keep them in production long, which didn't give customers time to discover they existed.
