The one thing this bozo is right about is no way you can put a panel on the wall for less than a grand. They can't be anyone else's panels, those guys don't even know about all these invisible astronomically non-existent non-risks. We cannot even begin to estimate the cost of room treatment until we know your net worth.
And I know what you're thinking, but we already know your gullibility and susceptibility to BS is sky high, or you'd never watch these stupid videos. So all we need now is your money.
