Hello friend today I ANUBHAV Rawat will tell you about this air cooler that I have purchase last year from Amazon at very highly cost and I have very bad feature as per my opinion this is my worst choice till.We have to wake up at mid night because of it bad sound and warm air this cooler very fatally get worm water this give us average service and the guide book which we get with this cooler it is totally opposite to its function so it is waste of time to to read it this is big and heavy this dangerous for us.So I will recommend you to buy after checking it .
