Hello this is my emberassing experience with this cooler.
Please do not buy this object Hitek air cooler.
Cooling and sound: -Worst cooling experience, sound will come like some engine is operated. I have ever seen in the cooler with the AC has written to draw the perfect ice-flow technologies, please do not believe this.
All parts of very low quality. durability is not upto the mark. And after the guarantee period will start creating problems.
This is a waste product from the company. please do not buy this
