SAVCOOL SUS #304 Smart Roof Vents, Roof Ventilators working 5 times more in heat exhaust than Wind Turbine Type (Big Discount on wholesale purchasing q'ty over 6 units)

I suppose you may find lots of cheaper metal roof vents including wind turbine type online. do you really understand why our smart roof vents work 5 times in heat exhaust more than wind turbine type? everything which works must have its scientific grounds. The key reason is that appearance shape and angles of our roof vent which are calculated precisely must be able to create "Bernoulli's effect" which enables ours generating 5 times more in heat exhaust than wind turbine type, so don't just feel our roof vents which look simple and expensive, but actually ours are powerful and deserve high pricing based on Bernoulli's effect. Do you find the cheaper ones say they work on Bernoulli's principle?
