Hello frnds it is a good product and also available very cheaply.a good product to try on and keep yourself cool in this hot summer.I have listed some more information about this product which given below.* It has a powerful air through of 9.1m* it has a capacity of cooling a room which is 13.9 square meter* It also has an air delivery of 1800 cubic meter per hour* It can also go to its peak speed that is at 100 and 1300 cubic meter per hour at an average speedThis is much more enough for an average family to keep themselves cool in this rising temperature.and I would personally recommend a simple family to purchase this product and this can keep them cool.
