I think the problem will be the promise of causing lucidity. If Ezo was woken 50% of the time and then managed to DEILD 50% of those time his sucess rate would be 25%. But what about people who wake 50% of the time, don't become lucid 40% of the time and become lucid 10% of the time with DILD because of the flashing lights. They would probably be people with some and perhaps much lucid dreaming skill. I think many people would likely almost never become lucid from these devices and give up.
So I don't think the devices will cause tons of new lucid dreamers, they will be tools for those who know how. The real advantage for the 10% induction in those who are knowledgeable in LD is that by using REM detection at the onset it will increase dramatically the stabilization and length of the dreams.
