Kenstar Double Cool DX CW 01 is a robust air cooler from Kenstar. It is immensely popular in cities like Dhanbad and surrounding areas where weather is too dry and hot in summer. I purchased this air cooler when I was staying there for a project work.
It has been providing good service till now since its purchased around 2 years ago. Weather of Kolkata in summer is a bit humid, so air cooler is not of much use, but with the extreme heat wave in the air specially in noon time, I turn on this cooler to get some cool air. This one particularly gives very cool air in a rapid pace. You can also direct the way of the wind using the feature like "Wind Rotator". It is also having a feature " Water Indicator" in order to make you understand how much water still left in the cooler. It does not make much noise like some other coolers and more or less similar to the sound of a pedestal fan.
But, presently I am having the main problem with this cooler is related to space. It is not like nowadays sleek looking cooler, it is a heavy one and occupies large portion of your room. So, moving around is also a bit difficult with this cooler where as with sleek cooler, you can easily move them one room to another as per you requirement. Water storage is another issue. It needs approx 15 litre of water daily if you want to get cool air whole night. I seldom use it for whole night just for this reason.
But overall, I am recommending it as I purchased this product only for Rs. 5400. So, if you have just relocated to a new place for shorter duration, you can easily try out this option where air condition seems to be a costlier choice.
