I want to buy jumbo air cooler because I show this cooler at one party. this cooler cools the room very well. it has big water tank so it works smoothly for long time. the cooler works on dura-pump technology of cooling so it throws the air with more power. this all things I ask to the party organizer. he also told me that the cooler comes in very nice price. it also has trolley for moving so I can move it easily. I will buy this cooler in three months because I like it so much.
