Review on VP 4 by Wiktor Janusz ᠌

Absolutely true statement that the quality corresponds to the price. I installed a fan three times more expensive in a harder case in the adjacent channel, so it didn’t bend under the channel, but straightened the channel to fit the shape of its case, as a result of which there is no hum or vibration, but in the channel where this fan was installed , AURAMAX VP 4, a rumble appeared, the vibration was removed by seals. I won't buy it a second time.
