This cooler is unable to satisfy the function.
It just passes normal air like a fan.
Though we pour icy water in it, the air breeze is not cool as per expectation. It is slightly cooler than outside air in sunny days.
One more drawback is its noisy working. It genrates a lot of noise such that it may interrupt your sleep.
So I am unsatisfied as per its function and cost.
Only good thing about it is portable and durable.
