I don't know, never having met the man, but I have met and talked extensively with Alan Markowitz who has done a fair amount of marketing for Oleg.
My take, and I emphasize MY take from observing what Alan was going through and from my own experience, is that Oleg is quite a talented instrument genius, and like many other genius's, he stumbles over the marketing and promotion of all his work.
I have one of his metal mouthpieces, three of his fabulous ErgoPlus neck straps, key risers, and yes Olegatures too, and more. They're all excellent products. But a great product without great marketing becomes history's also-ran. Sad.
