I have been using this product for last three months and I found so many better results. This fans are made up by using aluminum material and they consupt the power of 80 watts. This fans rotate in the speed of 380 rpm. These fans give high air delivery even at low voltages and these fans contains three blades. These fans have longer life with better cooling amd comfort. The look and design of these fans are also very amazing. So this bajaj company fans are best for good comfort in a very valuable price.
