Don't bother me a bit... I'm a 50 year old American... The Russians can either ramp-up production / availability, and offer the same unit at a price- point comparable to the clone, or as a consumer, I will buy the clone. Why would I want a "Lite" version??
I'd rather buy the kayfun Lite because I'd never use the adjustable air control and the filling valves have a tendency to die. Also more importantly it's shorter as a result.
