Hi friends I am using kenstar turbocool dx air cooler since last two years. The kenstar turbocool I am purchased with cost of 8999 in anantapur district. The kenstar cooler is do not giving any cooling it is giving only normal air sometimes the kenstar cooler giving hot waves that is why I suggest all the users don't purchased this type of air coolers. I think ac's is best for the air cooling. This type of coolers not controlled weather. The ac's are totally controlled to room temperature and weather that is why do not purchase any cooler. This type of coolers also maintenance is very high rates.
