In the summer we were bought a Symphony Cooler.and it is good first we were thinking that it will not worked properly because it is made up of plastic but when we were start this cooler we will be shocked that only few minutes later we will notice that full room will became a cold like we were starting the airconditionar.on the my point of view this product is good and this is since from 4 years in my house and we donot get any problem from this. There water storage are also so good and full night they will became a room as a airconditionar. Thank you
